(CNN) - Democrat John Edwards told CNN Tuesday that rival Barack Obama is likely to come under heavier scrutiny now that he appears to be the frontunner for the Democratic nomination.
"He's newer to this than I am, or Sen. Clinton," Edwards told CNN's Jessica Yellin at a Manchester polling station. "I've been through a national campaign. I've been vetted by a national campaign. And Sen. Obama is newer. I think he's going to be tested. And we'll see what happens."
Edwards is set to hit several events in Manchester as Granite State voters head to the polls. The latest polls indicate Edwards is in a distant third behind Obama and Clinton in the state, though the former North Carolina senator pledged in the interview to keep his campaign going through the convention no matter what the result.
"This is not about me, I've mentioned me being the underdog candidate. But I am nothing compared to the underdog that's the middle-class and low income families in this country," he said.
