It's a fairly Democratic seat left open by Mike Udall's Senate run this fall, and the Republican being offered up as a sacrificial lamb doesn't have much chance from what I read. By all accounts, this is the big election there, and he's very likely to be in the Congress this fall. It'll make him the first gay man to win a seat in Congress out of the closet in his first run, the second LGBT person to do so, and the sixth LGBT person in Congress ever.
Jared Polis wins in ColoradoFollow alexblaze
His politics seem pretty good from what I read of his stands on Iraq, immigration, the FISA, and civil rights. Polis was just endorsed by ActBlue (they didn't take a stand on the primary because Polis's challengers were progressive as well), and I would imagine he'd be a great Representative relative to the others who are already in the House.
