Vice President Joe Biden's new anthem seems to be, "We will, we will shock you": On Sunday he brushed off forecasts of the Democrats' demise as premature, insisting that the party will not only hold its head above water in the 2010 midterm elections but will be in "great shape." Biden told ABC's This Week: "We're going to win the House and we're going to win the Senate...I don't think the losses are going to be bad at all." Meanwhile, Republicans have been singing a different tune, taking to talk shows to trumpet their party's resurgence: National Republican Congressional Committee Chair Rep. Pete Sessions said that the GOP would be able to take back control of the House. Biden chalked up predictions that the GOP will best Dems in the fall to polls taken too early in the campaign season: "This is July," he said. "The most vulnerable time any public official finds himself in is when they have no opponent."
