Biggest flop candidate this election cycle?

[tmthforu94]

Torn between Braley and Rounds.

I'm not going with Roberts, because while he was originally favored to win, his approvals have always been murky and no one would have suspected that his ultimate opponent would be a wealthy Independent - he would have been considered vulnerable from Day 1 had that been known.

Rounds has consistently polled weak, and like Roberts, is in a race people would not have originally suspected. He's also still favored to win, so it's hard to consider a winning candidate "a flop."

Thus, I'm going to go with Braley. This race was considered favored for the Democrats the second Latham passed and Braley jumped in. He gave up a moderate lead despite having a very conservative opponent who has made a couple gaffes. He is also the one of these three that I think is most likely to lose on Election Day.
