In the days since, close to 30 superdelegates have swung behind Obama, evidence that party officials are beginning to coalesce around the first-term Illinois senator who is seeking to become the first black to win a major party presidential nomination. Three of his new supporters formerly backed Clinton, who surrendered her lead in superdelegates late last week for the first time since the campaign began.

In his appearance in Cape Girardeau, Mo., Obama sketched the case against McCain. "For two decades, he has supported policies that have shifted the burden onto working people. And his only answer to the problems created by George Bush's policies is to give them another four years to fail," he said.

Tucker Bounds, a spokesman for McCain, said in response that Obama's rhetoric showed "more of the same negative, partisan politics that have paralyzed Washington for too long. Barack Obama talks about change and bipartisanship, but he has never showed the leadership needed to bridge party divides."

Clinton had spent parts of several days campaigning in West Virginia in search of victory.

She refrained from criticizing Obama directly, but had a cautionary word nonetheless for party leaders who seemed eager to pivot to the fall campaign. "I keep telling people, no Democrat has won the White House since 1916 without winning West Virginia," she said at Tudor's Biscuit World in the state's capital city.

Obama was in the state on Monday, but it was clear he was looking beyond the primary.

He said several days ago he expected Clinton to win by significant margins in West Virginia and then in Kentucky, which holds its primary next week. He devoted more time to Oregon, which also holds a primary next week, and announced plans to campaign in several other states that loom as battlegrounds in the fall against McCain.

Among them are Florida and Michigan, two states that held early primaries in defiance of national Democratic Party rules. The two combined have 44 of the 270 electoral votes needed to win the White House, and Obama has not yet campaigned in either.

Obama also broke from his usual practice by wearing a flag pin on his suit jacket. He told several thousand people at the Charleston Civic Center that patriotism means more than saluting flags and holding parades.
