Most vulnerable incumbent Senator in 2014?

[JerryArkansas]

IMO, easily Mark Pryor.

I voted Begich, but reading the rest of the comments, I changed my vote to Pryor. I was unaware he was in that much trouble and I have not really followed his race.

Right now, people are pissed at him.  he is at about 40% in polls right now, which given his name rec, is horrible.  His approval rating is bad too.  30% approval/disapproval, just bad.

In order:

1. Pryor (nearing Lincoln levels)

I'm not that familiar with Arkansas politics, so what the hell did Pryor do to approach Lincoln's territory and less than six years after running basically unopposed?

Being a Dem who is being portrayed as close to Obama.  Health Care vote, and other things have hurt him bad.
