Could Todd Akin be next Christine O'Donnell?

An article on the Washington Post's Political Fix blog questions whether a Todd Akin win in today's GOP U. S. Senate primary would be akin (sorry about that) to previous elections that have put unelectable candidates such as Sharron Angle and Christine O'Donnell in the general election:

The latest polling of the race shows Brunner leading, but it’s anybody’s ballgame, and Akin appears to be the momentum candidate (what’s more, his base, religious conservatives, may be the most reliable voter bloc). Democrats seem to think getting Akin through the primary would do wonders for them, and they’vespent a bunch of money in the GOP primary trying to make that happen. The congressman gives them an opening as someone who is very conservative, doesn’t have a history of tough campaigns, isn’t terribly compelling personally and, perhaps most notably, has declined to go negative in his campaign. That could be a recipe for success for McCaskill.But what we’re forgetting here is that basically none of these candidates has set the world on fire, and the reason the GOP can beat McCaskill is that she’s in such a bad position right now.
