I just came across mention of Scott Brown, candidate in Massachusetts running for Sen. Kennedy's vacant seat in a special election to be held January 19th. He is against the current healthcare bill, and against cap-and-trade, but also seems to be a typical proponent of mixed-economy solutions to these problems. Still, he would be better than someone who would support the Democrats on these two policies.
Check him out. If you find him reasonable, consider donating to his campaign and spreading the word.
Rasmussen Report on the Massachusetts Senatorial race. This has some interesting details on the dislike of MA's health care with the state, and on the fact the race may be closer than the raw numbers (50% Coakley, 41% Bown) indicate.
More on the race at Keller @ Large blog.
The Washington Post has a different take on the race, apparently, the GOP is not providing much financial support.
According to this article, Brown supports treating Abdulmutallab, the Al Qaeda Christmas bomber, as an enemy combatant, not a common criminal and does not consider water-boarding an illegitimate interrogation technique. He showed poor taste and judgement in a 2007 speech to a high school, and is against gay marriage.
That's about all I can find for now.
