According to the Washington Post, Congressman Paul Broun who somehow got a medical degree, is already causing some Republicans to worry that Broun will say things that make him unelectable. Since Broun has already said such statements as "evolution, embryology and the Big Bang Theory are lies from the pit of Hell" and "the only constitution that Obama upholds is the Soviet Constitution", that sounds like a valid concern. However, GOP primary voters are very different from you and I, and they are certainly worlds apart from the Republican hacks that only believe in the Almighty Green. As seen by the example of Claire McCaskill, calling someone "too conservative" for your state can ensure that they win the GOP primary, and I really doubt any ad campaign would have sunk Christine O'Donnell winning the GOP primary. In fact, I wonder if some enterprising Democrats are already dreaming up a new front group to run ads like "The HMS Beagle Defenders", in which Broun is villified for being way too anti-science for Georgia, and that science clearly shows that climate change needs to be addressed. Perhaps another ad where Broun condemns "Inherit the Wind" for making the pro-evolution side in the Scopes Trial as heroic or something.
The Washington Post article notes that Club for Growth and the Senate Conservatives Fund have not taken a side yet as far as the Republican field, and it implies(and there is also a Christian Science Monitor article that Karl Rove would have his first test case) that some Republican organizations may try to kneecap the Tea Party and submarine Broun's candidacy in the GOP primary. I look forward to whatever the national GOP plans to do if they want to sell Karen Handel(someone so anti-choice that they trashed Komen for the Cure's reputation) or Phil Gringey(who said Akin was partially right about his rape comment) to Georgia voters.
I also look forward to Democrats being aggressive about fielding a strongly progressive candidate for Broun's House seat(GA-10). The Georgia 10th is a R+14 district, but it contains Athens, which is the home of the University of Georgia and a very progressive city. It would be interesting if the eventual Democratic nominee for the GA-10th could use the members of the B-52s or REM(both local to Athens) to help excite young voters. I personally would like to see if Tim Riley, an openly gay mental health counselor from Athens who has run for State Senate a few times, wants to try for Congress. I could see the netroots being excited about a candidate like Riley. If Riley decides to run again for State Senate, I will also highlight that race sometime in the future(as state legislative races get little attention here on Daily Kos)
