"It's shaping up as a Republican wave," Bayh said. "The question is how many Democrats can find their way to the high ground? I think if we are successful in localizing and personalizing as many of the elections as possible it doesn't have to be a complete disaster."
Bayh said he still held out hope that Rep. Brad Ellsworth, D-Ind., would beat former Sen. Dan Coats, R-Ind., to take Bayh's open Senate seat.
Even former President Clinton, currently on the trail, has expressed frustration.
"He believes that we [Democrats] have lots to be proud of and thinks we could do better at framing the debate," said a source close to the former president.
Behind closed doors recently at a fundraiser, Obama blamed Democrats' difficult election cycle partially on American voters' fears making them irrational.
"Part of the reason that our politics seems so tough right now, and facts and science and argument does not seem to be winning the day all the time, is because we're hard-wired not to always think clearly when we're scared," he said. "The country is scared and they have good reason to be."
