Obama wins Maryland, Virginia, DC, Hawaii, and probably Wisconsin. Even though these states have been "priced in" by the blogs and political junkies, low-information Clinton voters finally consider Obama as more than just the other name on the ballot. Major endorsements and most media moves to Obama. A small media backlash about Obama supporters as a "cult" fails to take root. Ohio goes to Obama, Texas to Clinton by 10% or less. Obama wins the nomination without any kerfuffle over superdelegates.

Obama wins the general election in a realignment. "Not since Reagan" is repeated on election night by every talking head.

Democrats widen their margin in the Senate. Harry Reid is ousted or steps down as majority leader. The House stays pretty much the same.

Claire McCaskill voting to extend the Bush tax cuts?

Not a reality-based statement.  

Link.And, you think a Democratic Congress would extend those tax-cuts with President Obama approving?

That's beyond silly.  It's somewhere between insane and libelous.

Obama not arguing that we need more Democrats in Congress?  He talks about the need to build a working majority every chance he gets.  He's campaigned for Democrats every chance he's gotten.  He's asked his supporters to phone bank for Democrats in the special House elections.

Your disagreement with his rhetoric has rendered you incapable of discussing him rationally.

You're now in the same league as Taylor Marsh.  

It is dishonest for you to describe yourself as an Obama supporter, since you are indistinguishable from Taylor Marsh when it comes to him.

My big prediction is that we won't win, no matter who our nominee is. Our nominee isn't Bill Clinton and their nominee isn't Bumpkinish George W. Bush. McCain puts places like Pennsylvania and Connecticut back in play for Republicans. Hillary can win Florida, and Obama can't. Likewise for Ohio. The reverse is true for Iowa.

Senate:

Both Udalls win, Mary Landrieu Loses. Al Franken is elected by 100 votes--the closest margin in the country. John Sununu is toast. John Kerry runs a closer-than-expected race.

House: We pick up 5-10 seats. Nick Lampson and Tim Mahoney lose anyway.

McCain keeps us in Iraq for ages, but "accidentally" appoints another David  Souter when Stevens dies.

Health Care will pass there is not choice,

Nelson, McCaskill, Kerry and Kennedy will lose their seats to younger less divisive candidates when they come up for re election.

She will not roll back the tax cuts under 250,000.

She will severely restricts discretionary spending,

She will have coat tails. Pulling my local candidate into office in an open Republican seat.

We will prosper

There will be gun control, more police and crime will drop again

Lou Dobbs, Chris Matthews, Rush will be fired for being stupid and no one will visit Huff Post anymore.

And We the People will stand up and do our part and fight for honorable ethical competent governance and protect our leaders from the loons.. instead of boo hooing and playing victim corrupt people and special interest

Wisconsin and Virginia are critical states in the general. Very relevant. (Colorado, Minnesota and Iowa are relevant too.)

Further, here's a list of states that Obama won on our side but McCain did not. That says something about the general:

I do agree that if Obama runs the general election like the primaries, there will be no mandate for anything except maybe "can't we all just get along".

Even if there is a ton of republican and media against any democratic agenda, it would be a real shame not to push for all it's worth.  

In 2012, after rolling back the Bush tax cuts and enacting universal health care reform, Clinton loses her reelection bid to Bobby Jindal, the Governor of Louisiana. Democrats lose the Congress.

For the primary, I think Obama wins out February like they both admit, then works TX really hard to prove his chops with Latinos, makes it close, then carries OH on the strength of Cleveland (blacks), Columbus (elites), and a strong organization in the other college towns like Dayton. PA goes to Hillary, but Obama makes it a draw again, making it impossible for her to overtake his lead once he takes it this month.

General: He beats McCain all around, 270 is not a problem, and the turnout he brings does add to the Democratic Congress, making it easier for him to govern (his ruling majority theory). I think Iraq proves harder to get out of than we admit right now, and he doesn't go as far on healthcare as we would like, but he does improve our image around the globe, doing good work on weapons and disease, and has a solid two terms.

For Hillary, she could surprise him in WI, proving the theory that bigger states just don't work for him, she keeps her Latino vote in TX, and then the SD's make it clear to Obama that he has to get out of the way.

The GE will be ugly, but she comes away not as battered as she could have been. She'll move hard to the center, following her husband's lead, maybe staying a little left of him, but she does lose the midterms, gets tangled in GOP scandal hunt, and does lose in 4 years. Romney will be there to make good on his earned favors, and the Clintons go back to writing books and making speeches, doing the kind of good work they're really made for.

First off, Clinton or Obama coattails aside all indications are there will be a gain of around 4 seats in the Senate. This will make certain things much easier to pass for whichever of them wins.

I'm also not sure how easy it is to quantify the "coattails" phenomenon.  You have to compare how the other candidate might have done.  You also don't mention that the Republicans have had years to work themselves up into an anti-Clinton fevor, driving out the base.  I'm not sure they can replicate that quite so quickly against Obama.  (But this may just be my bias shining through.)

IN ANY CASE...

The idea that an Obama presidency would compromise liberal principles beyond recognition is little more than a Clintonite talking point. Obama's history shows that, ideologically, he is as progressive as they get. Big Tent's Fallacy is the idea that you can only achieve what you want by demonizing the opponent; Obama intends to both fight for core liberal principles and, at the same time, remain civil.

If the young voters instead lapse into apathy and fail to remain politically engaged because they haven't been inspired to, America continues down the nondemocratic path it's currently on.

in short, the Rs know Clinton is the stronger candidate of the two and are helping him along so that come the GE, they'll tear him to shreds.

No coattails for Obama.
This seems very couter-intuitive. And it also is at complete variance with the opinions (far better informed than any of us) of actual Democrats out there, especially in the purple and red states. They very much want Obama on the ticket because they think he would help them downticket, and Hillary would be a disaster.

Obama mandate based on nothing but ending War.

This makes absolutely no sense to me. Obama will ahve no hesitation laying out an economic and social agenda. In fact, it is the obvious thing for him to do. Against McCain he merely needs to assure the country that he is basically competent on foreign policy, then he has the economic field pretty much to himself. McCain cannot argue credibly against the Dem economic program, so there will be no need to not put it forward prominently.

Tax cuts and health compromised.

This makes NO sense whatsoever. Obama will have expanded majorites in both the House and Senate. For the tax cuts to be extended, they need to pass Congress. How on earth do you think a Dem. Congress is going to pass such a bill? Remember, the tax cuts expire on their own if nothing is done.
Same with health care. Who is Obama going to have to compromise with? All we will need is 3-4 senators to avoid a filibuster, and there are, I bet, that many who would gladly sign onto his proposal as is.

the hillary clintons, on the other hand, know how to grind things through.  our current vp has been extremely effective at pushing his agenda despite most of the country hating him, as was bill even in his darkest days.  political magic is overrated.

my prediction is still (though not previously mentioned here - i'm new) that she'll win the nom.  sure, its scarey now, but they thrive on this stuff and she's demonstrated her bedrock support.  she won't wither where others would.  in the general, mccain will have a few percent sucked by a spoiler (running on immigration, values, 'fair' taxes and distrust of mccain) and hillary will waltz into the white house.  obama would waltz in too.  

with or without the spoiler the dem will win, it will just be a closer vote.  electorally it won't be so close.  as devisive as hillary is, blah blah blah, the dems are ripe. they'll run a smart campaign, mccain won't excite the repubs, and we're going to take florida and ohio (the vote stealers don't run ohio anymore and that alone gives us the general.)  a combo, as btd has suggested prior, would produce a realignment, but i differ on who's better off in charge.

regarding the dividing of the party stuff, i'm not buying it all.  that perception comes from spending a lot of time in places like this and/or the obama-loving versions.  most dems don't wallow in this and are still happy to vote for either.  all this 'leaving the party' stuff is silly emotions run amok and there's versions of it every time.

The overall state of the race seems to be that Obama has strong momentum and the Doyle firing isn't great for Clinton.  However, I wouldn't read too much into what's going on within camp Clinton.  The Clinton campaign has always been riven with backbiting and nastiness, and decisions have always been made by committee.  This won't change the basic emotional and panicky contours of her inner circle.

[Emphasis added.]

If BHO gets the nomination he wins 40+ states and a pickup in both houses against a somewhat divided Rep party.

I do not believe that Obama will offer, nor will HRC accept a VP slot on ticket. (If Clinton were to miraculously win nomination, I believe she would offer Obama VP, though I'm not sure he would accept).

In the General, either will win election, though Obama might have a tougher time. With either, the Republicans (and the MSM) would wage the ugliest campaign in the history of the nation.

As president, Clinton would pass universal health care, Obama would not but might vastly expand what we have now.

Clinton would get us out of Iraq in an orderly way and work through diplomacy to get some kind of regional settlement. I think she would make real headway in Israeli/Palestinian conflict.

Obama would attempt to exit Iraq, but would do so less smoothly with less international and regional support (because of less diplomatic and military expertise).

Clinton would get a strong economic program through Congress and would have very strong team on economy in Treasury and other cabinet posts.

Obama's policy on Social Security and taxes is my biggest worry, and I fear he would govern fairly conservatively in this area and cede too much ground to Republicans.

With an Obama presidency, the nation would begin to have a different image of itself, as a black president would be an enormous sea change.

Remember the CW after New Hampshire? It went like this: Obama was poised to win the state big. But thanks to the poll numbers and the post-Iowa premature coronation of Obama, independent voters conflicted between McCain and Obama decided to switch their vote to the Republican contest. If the Democratic nomination was already decided, they apparently reasoned, why not vote for the other guy we liked?

In upcoming open primaries, with McCain taking the clear lead as GOP nominee, that dynamic won't be operative, favoring Obama in Guam, Hawaii, Indiana, Mississippi, Montana, Ohio, Texas, Vermont, Virginia, Wisconsin, North Carolina...
