Mourdock (Indiana)
Akin (#legitimate Rape) Missouri
Berg - (North Dakota)
Angle (Nevada)
Raese (West Virginia)
Buck (Colorado)
You can argue a couple of these (maybe WV and Col) But you have to believe in 2010 (which had a higher GOP vote than 2014) that mainstream GOP candidates could have picked off a few more senate seats....
The three seats where Republicans screwed up royally with gaffe-prone candidates were DE, IN and MO.
Manchin was a popular governor in WV and possibly the only D that could have maintained the seat.
I don't think it was as much as Angle was a terrible candidate (for NV) than Harry Reid is a master at ground game there. The result would have likely been the same no matter who he ran against. He's basically Houdini.
Berg wasn't the best candidate in ND. But she wasn't really a tea partier.
Colorado was just what it was at the end of the day.
