So we've gone from 12 Democratic Senators and 9 Democratic Congressmen to what will very likely be 5 Democratic Senators (all elected in 2012) and 5 Democratic Congressmen in Romney Districts. Wow.
What about Senate Republicans in Obama states? This is why Republicans have a majority currently, since we most of the red state Dems this year.
Cory Gardner (CO)
Marco Rubio (FL)
Kelly Ayotte (NH)
Chuck Grassley (IA)
Joni Ernst (IA)
Mark Kirk (IL)
Susan Collins (ME)
Dean Heller (NV)
Rob Portman (OH)
Pat Toomey (PA)
Ron Johnson (WI)
Also, only 3 of the 5 Romney Dems have ever survived a midterm (McCaskill, Manchin, Tester) and only 3 of the 11 Obama Repubs have ever survived a presidential year (Collins, Heller, Grassley).
