GRINNELL, Iowa (AP) - Vice President Joe Biden is focusing much of his two-day Iowa trip on blue-collar areas, hoping to improve President Barack Obama's chances of carrying the state he captured in 2008.
Biden campaigned Monday in Burlington and Tuesday in Ottumwa before capping the visit with a stop at Grinnell College.
While college students are a strength for Democrats, white working-class voters like those who populate the small manufacturing towns of southeast Iowa have been a weak spot.
Polls show white voters without college degrees prefer Republican Mitt Romney.
Speaking at the Port of Burlington, Biden noted that Obama's support for the 2009 automotive industry bailout helped Burlington's Champion spark plug factory.
In Ottumwa, he promoted Obama's proposal to reward companies that move jobs back to the United States with tax credits.
