The incumbent members of Congress running in the Connecticut [5], Nevada [3] and Colorado [4] primaries all survived their same-party challenges Tuesday.

In one of the two open House seats (both in Colorado), retiring Rep. Tom Tancredo [7]'s heavily Republican 6th congressional district, Colorado secretary of state Mike Coffman [8] won the GOP nomination. In the other, Colorado's 2nd congressional district, Jared Polis [9] (and the millions spent out of his own pocket) beat out the crowded field to represent the Democratic Party. Polis’s victory almost guarantees his victory in November – the district is very Democratic, so Republican challenger Scott Starin [10] definitely has his work cut out for him.

Colorado is also home to the only open Senate seat, currently held by retiring Sen. Wayne Allard [11] (R). Democratic Rep. Mark Udall [12] and former Bob Schaffer [13] (R), were uncontested in that primary.

Probably the most vulnerable incumbent in these states come fall is Rep. Chris Shays [14], the last remaining Republican in the House from New England. The Democrats in that district overwhelmingly nominated Jim Himes [15] to challenge him in the general election.

As part of Congresspedia's Wiki the Vote [16] project, citizen journalists from around the country (and even some candidates!) have been logging information about the candidates' positions, biographies and records. We’ve also started displaying the candidates’ biggest campaign contributors on their profile page.

A full list of the candidates and their professions are after the jump, but you can also find them at their respective state portals via the Wiki the Vote project homepage [16]. We need your help to find out more about these candidates, so if you know something about them please add it to their profile. (You can always contact [17] one of the staff editors for help.)
