While the two Democratic presidential rivals hit the campaign trail again today, party leaders are about to try to make it stop.
Tuesday is the final day of Democratic presidential primaries. Top party leaders say that when it's over, they'll push uncommitted delegates to make up their minds and back either Barack Obama or Hillary Clinton.
Clinton heads back to Puerto Rico today to meet with voters in Old San Juan. Puerto Rico holds its primary Sunday and Clinton is favored to win.
Obama holds a rally in Great Falls, Montana. Montana and South Dakota hold the last of the Democratic primaries Tuesday. The AP's count shows Obama is within 44 of the number of delegates needed to capture the nomination. He stands to gain at least 20 delegates in the three remaining states, even if he were to lose all three.
Republican candidate John McCain campaigns in Wisconsin Thursday. His agenda includes an informal meeting with reporters.
