Colorado: Lamar Alexander

Colorado freshman Sen. and Deputy Whip Mark Udall is a pivotal figure in the intended Obama revolution, according to a profile fronting today’s Congressional Quarterly. Udall’s tall-order task is to help Obama succeed where Ronald Reagan failed by getting the record-breaking number of majority party newcomers in the senate to support the president’s agenda without alienating the moderate voters who elected them.

The list of newcomers Udall is tasked with wrangling includes two fellow Democrats — the other senator from Colorado, Michael Bennet, Interior Secretary Ken Salazar’s replacement; and Udall’s first cousin, Tom, from New Mexico.

Although Mark Begich of Alaska is the only freshman Democrat from a state that voted for Republican John McCain in November, five of the new Democratic senators were elected in states carried by George W.
