(CNN) - Frustration with the economy led to an incarcerated man winning 40% of votes in the West Virginia Democratic primary earlier this month, Vice President Joe Biden said Thursday.
In an interview with WTOV, Biden said he doesn't "blame people, they're frustrated, they're angry."

"When you're out of work, man, it's a depression," Biden told the CNN Ohio affiliate. "And a lot of people are still hurt because of this Godawful recession we inherited that cost 8.4 million jobs before we could really get going."
The vice president was speaking in Martins Ferry, Ohio, on Thursday, touting the improving auto industry and relating his own middle-class background to experience of many in this battleground state.
But while voters may be frustrated now, Biden said he believes voters will decide he and President Barack Obama are better suited for the White House than GOP candidate Mitt Romney.
"They're going to decide, is the way back to their employment, is the way back to them being able to have a job and raise a family - is it under the values set and the ideas of Romney, or is it under ours?" he said. "And we feel confident we'll do just fine."
Keith Judd, inmate #11593-051, is serving a 210-month sentence in a Texas jail for extortion. He met all the parameters for getting on the West Virginia ballot and received 73, 138 votes to Obama's 106,770 in the primary held on May 8.
