Washington (CNN) - He's traveled from coast to coast trying to help fellow Democrats. But on October 7, President Barack Obama won't have to make such a long trip.
A Democratic source confirms to CNN that Obama will team up next week with Maryland Gov. Martin O'Malley, who's running for re-election this year.
News of the trip, first reported by the Washington Post, came Tuesday as the president's voice appeared in a new radio ad for the first-term governor.
O'Malley faces off in November against Republican challenger Robert Ehrlich. In 2002, Ehrlich become the first GOP governor of Maryland since Spiro Agnew, but he was defeated in his 2006 re-election bid by O'Malley, who was mayor of Baltimore at the time.
A new Washington Post poll released Wednesday indicates that O'Malley leads Ehrlich by 11 points among likely voters. Other recent surveys have suggested O'Malley holds a single digit advantage.
According to the Post poll, Ehrlich is overwhelming winning the Republican vote and holds a wide advantage over O'Malley among independents, but he's not grabbing enough cross-over Democrats, as he did eight years ago. Democrats greatly outnumber Republicans and independents in Maryland.
Even though incumbents are facing a difficult political climate nationwide, the survey indicates nearly two-thirds of likely Maryland voters have a favorable view of O'Malley, with just one in four saying they see him in a negative way.
The Washington Post poll was conducted Sept. 22-26, with 1,448 adults, including 730 likely voters questioned by telephone. The survey's sampling error for likely voters is plus or minus four percentage points.
