Rep. Eric CantorEric Ivan CantorRace for Republican Speaker rare chance to unify party for election Scalise allies upset over Ryan blindside on McCarthy endorsement 2018 will test the power of political nobodies MORE (Va.), the second-ranking House Republican, said that the freshman Virginia Democrat has voted in lockstep with the Obama administration, a choice he says will hurt Perriello among voters in the state's traditionally Republican 5th congressional district.

"I'm disappointed he's not bringing in Joe Biden and Nancy Pelosi too," Cantor said on a conference call with reporters. 

Cantor's comments came hours before Obama is set to headline a Charlottesville, Va., campaign event for Perriello, who backed the White House on several major legislative items over the past two years.

Perreillo's race has been one of the most closely watched House contests this cycle, and Obama's visit has thrust it further into the spotlight. Democrats hope that the president will drum up enthusiasm among voters that helped carry Perriello to a narrow victory in 2008. 

Perriello voted for the stimulus, healthcare reform and cap-and-trade energy legislation, but voted against the financial regulatory reform bill, saying it did not go far enough. Unlike other endangered Democrats, Perriello has not shied away from his voting record, which contains votes for key Obama agenda items.

Republicans, however, are pouncing on the stop, saying that it shows the desperate position Democrats are in to hold on to control of the House and using it to tie Perriello to Obama and Pelosi, who are unpopular with the public. 

"We are looking at [Obama's] visit as something that really brings into focus the real question in this race," Cantor said.

The Democratic Party of Virginia criticized Cantor and Hurt in advance of the call and said GOP policies would damage the economy.

"Most of what you’ll hear from today’s conference is more of the same, which is fiting cause most of what’s offered by Cantor-Hurt Congress is more of the same policies already rejected by voters," the party said in a statement.

The Hill 2010 Midterm Election Poll, conducted a month ago, found Perriello trailing Hurt by just one point.
