Colorado Senator Wayne Allard, a Republican, announced today he will keep his term-limits pledge made before the 2002 election and step down in 2008. He said it's a matter of integrity.

"The people of Colorado placed their trust in me based on a promise I made to them and I am honoring that promise. In an age when promises are cast away as quickly as yesterday’s newspaper, I believe a promise made should be a promise kept."

Rep. Tom Tancredo, who in the past indicated his interest in the seat, should Allard retire, has repeatedly breached a similar term-limits pledge to Colorado voters. What does that say about his integrity?

It probably doesn't matter much, as Tancredo is off to Iowa to gauge interest in Presidential run which his spokesman admits would not be launched for the intent of winning, just to raise attention to what seems to be his main purpose as a politician, kicking undocumented residents out of the U.S. Today he said he's not interested in the Senate seat.
