Veterans, about 13 percent of the adult population and consisting mostly of older men, support Mitt Romney over Barack Obama for president by 58 percent to 34 percent, while nonveterans give Obama a four-percentage-point edge, according to Gallup.

"Obama and Romney are tied overall at 46 percent apiece among all registered voters in this sample," Gallup reported. "Men give Romney an eight-point edge, while women opt for Obama over Romney by seven points.

"It turns out that the male skew for Romney is driven almost entirely by veterans," Gallup says.

Obama gave Memorial Day remarks today at both Arlington National Cemetery and the Vietnam Veterans Memorial in Washington, D.C.

Romney appeared at a Memorial Day event in San Diego with 2008 Republican nominee -- and Vietnam veteran -- John McCain.

Four years ago, McCain beat Obama among veterans by 54 percent to 44 percent.
