Unless the GOP nominee starts opining on the female reproductive system, the turnout in a midterm will likely doom Hagan. Dems' best chance to hold the Senate is by holding Louisiana, Michigan or Mnt, Alaska, and winning KY or NC.
Not at all. A lot of Democrats/Independents who don't normally vote in the midterms are angry and will be trying to vote out the Republicans in the general assembly and a lot of them will probably vote for Hagan (and anyone else with a D).
Hagan's biggest task is to get the marginal Romney voters (especially Obama 2008/Romney 2012) to vote for her.
