Allard's seat is listed as a marquee race for 2008 and possibly one of the most likely to change hands.
Well, the most likely according to the Washington Post.
Colorado -- Wayne Allard (R): Allard has yet to make a decision on whether he will run for a third term in 2006. He had previously pledged to serve just two terms, and his meager campaign cash balance -- $119,000 -- seems to suggest he will keep that oath. Regardless of whether Allard runs, Democratic Rep. Mark Udall is in the race and is the likely frontrunner; he showed more than $1.2 million on hand just prior to this month's election. Another name mentioned is Denver Mayor John Hickenlooper, but after his long -- and ultimately unsatisfying -- flirtation with the 2006 governor's race, we aren't waiting with bated breath. Should Allard step aside, expect former GOP Reps. Scot McInnis and Bob Schaeffer to look seriously at running. Former Gov. Bill Owens's name will also be mentioned but that seems like a longshot at the moment. Given Democrats' gains in the last two cycles in Colorado -- picking up two House seats, a Senate seat and the governorship -- this will be one of the marquee races of the cycle.

Should be an interesting race.
