On the campaign trail, Senator Barack Obama is inching toward victory as voters in South Dakota and Montana go to the polls today in the last primaries of the Democratic presidential race. Senator Hillary Rodham Clinton has publicly vowed to continue her campaign, but aides have hinted she’ll drop out of the race later this week. On Monday, Senator Clinton’s husband, former President Bill Clinton, also suggested her concession is imminent.

Bill Clinton: “This may be the last day I’m ever involved in a campaign of this kind. I thought I was out of politics, ’til Hillary decided to run. But it has been one of greatest honors of my life to be able to go around and campaign for her for president.”
