CNN is reporting that House Democrats hope to capitalize on Sen. Barack Obama's popularity in Congressional races around the country.
But House Minority Whip Roy Blunt of Missouri argues that the John McCain factor is also at play.
He says McCain is the Republicans' best chance to appeal to independents and working-class voters.
"I do think there's a presidential dynamic that's stronger than it normally is. ... I think the presidential dynamic works to our advantage ... and I think it does because of the unique appeal of John McCain to people who don't always vote for Republicans," Blunt said.
