You can choose up to 3 candidates.
I chose
Hagan,
Brown, and
Baldwin. All three of these would be accepted enthusiastically by the Democratic base, but none of these three would be seen by a majority of the country as too "out there." Brown is a populist progressive from a swing-state, popular in both Ohio and known nationally to the base. Baldwin made history as the first openly-gay Senator elected, and was a solid progressive in the House. Hagan is mostly centrist, but progressive where it counts, having recently come out in favor of gay marriage despite her state constitutionally banning it by a wide margin just a year earlier and being up for a potentially close re-election next year.
As for the rest... Bennet is not a natural campaigner or politician, and while he isn't despised by anyone he isn't celebrated by anyone either. Udall would be a good pick, but Hillary is experienced enough and she may want someone younger. Klobuchar would have problems with the base on civil liberties, and her mannerisms remind some of Palin. Heinrich could be good... but he's pretty much an unknown quantity right now. Kaine is not that well-liked in Virginia, and wasn't that good of a governor or DNC chairman, and hasn't really stuck out in the Senate yet.
Michael Bennet (Colorado)
Mark Udall (Colorado)
Amy Klobuchar (Minnesota)
Martin Heinrich (New Mexico)
Kay Hagan (North Carolina)
Sherrod Brown (Ohio)
Timothy Kaine (Virginia)
Tammy Baldwin (Wisconsin)
