Snippet:

Veteran Sen. Arlen Specter says President Barack Obama has promised to campaign for him in next year's Democratic primary in Pennsylvania.
Specter told reporters on Capitol Hill Tuesday that he spoke to the president about his party switch.

Separately, the White House said no promises were made to Specter to get him to switch parties and become a Democrat. Asked about Specter, press secretary Robert Gibbs told reporters that no promises were made to the veteran senator as far as he knows.
