The 2004 Presidential election represented a continuing trend of Hispanic/Latino voters away from the Democratic ticket. The 44% share of the Hispanic/Latino vote achieved by the 2004 Republican Presidential ticket surpassed the previous high of 37% for the 1984 Republican Presidential ticket (Reagan-Bush).
Although subsequent revisions of the Edison/Mitofsky National Elections Pool (NEP) exit poll reduced this share to 42%, the Republican Presidential ticket in 2004 won a greater share of the Hispanic/Latino vote than any other Republican Presidential ticket since the advent of Presidential election exit polls in 1972.
In the 2006 Congressional elections, Hispanic/Latino voters voted for Democratic candidates by a 19% margin. This represented a shift to the Democratic Party of 8 percentage points from 2004.
There is diversity among Hispanic/Latino voters nationwide. About two-thirds have roots in Mexico. The remainder includes voters with roots in Cuba, the Dominican Republic, Puerto Rico, and other parts of Latin and South America.
One conclusion: The Democrats can't take the Hispanic/Latino vote for granted. They are one of four key groups -- the others being older voters, women voters and Catholics -- that have trended towards Republicans in recent years.
Hillary does better with all four of these groups. It's one more factor the superdelegates should consider this week.

Update: BackfromOhio writes Pew Hispanic.Org has a report on Latinos in the 2008 Election that says Hispanics are now 9% of eligible voters and estimates they will be 6.5% of the voters in the Fall.
