O’Malley, the chairman of the Democratic Governors Association, is scheduled to spend much of the day campaigning in North Carolina with his party’s gubernatorial hopeful Walter Dalton.

O’Malley will appear at a fundraiser with Dalton, the state’s current lieutenant governor, in Winston-Salem and at a pair of public events focused on jobs and education in Greensboro and Raleigh, according to aides.

In polls, Dalton has been trailing Republican Pat McCrory, a former Charlotte mayor. A McCrory victory would mean the first GOP governor in in the Tar Heel State in 20 years.

Dalton and McCrory are vying to Gov. Bev Perdue (D), , who decided not to seek re-election. Perdue is vice chairwoman of the DGA, which attempts to expand the ranks of Democratic governors across the country through fundraising help and other assistance.

A top Perdue aide recently joined O’Malley’s political action committee. The PAC is among the latest evidence that O’Malley is working to increase his national visibility, with a possible 2016 presidential bid in mind.

O’Malley’s southern swing Thursday also includes an address to a conference of a major labor union, the United Association of Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada. The group is meeting in Ft. Lauderdale, Fla.
