At rallies, Mr. Obama seldom urges supporters to volunteer — or even vote — for other Democrats running for office. Sometimes, he mentions other politicians in the room without noting that they are seeking re-election. He rarely shares the stage with other candidates.

"He's ultimately there to communicate where he wants to bring the country and the differences he has with Mitt Romney. He's not out there campaigning all around the country for other candidates," a senior Obama campaign official said. "It's not that he doesn't want them to get elected, but it's a campaign event to elect him." …

"We really do believe a high tide raises all boats," said Obama campaign manager Jim Messina. "If we win, history teaches us Democrats will win, as well." Asked why the president doesn't usually mention other candidates in his remarks, Mr. Messina said there is only so much time at the start of a speech for preliminary thoughts. In any case, he said, the president can't simply bless a candidate and assume that will help; candidates have to build their own relationships with volunteers and voters.
