“I’m just not worried,” said Ray Allen, Cantor’s Richmond-based political adviser.

Neither is the candidate himself, who said he is treating the primary on Tuesday the same as any election.

“We have always taken every race seriously, and we’re taking this one seriously,” Cantor said in a brief interview Thursday as he was campaigning at a county fair in Culpeper. “We’re feeling really good about where we are and looking for a big win Tuesday.”

Cantor spent nearly $750,000 in his 2012 primary and came away with 79 percent of the vote against a token Republican challenger who spent just over $2,000.
