Warner's PAC is having a little contest to see which (mostly congressional) candidates will get money from the PAC, and the grand prize winner will get a fundraiser with Warner. As with all of these things I imagine it's in part a cunning plan to expand their email database, but if some of your favorite candidates are on there that might be a sacrifice you're willing to make.
My votes for this round are:
Rowley
Wetterling
Tester
Carter
Kennedy
Laesch
Skinner
Murphy
Murphy
Carney
But, choose your own of course.
