President Barack Obama wades into a fight among Democrats on Tuesday by attending a fundraiser for Sen. Arlen Specter, D-Pa., demonstrating an unusual measure of commitment in a primary whose outcome is far from clear.
As leader of his party, Obama had the option of staying out of the primary race between Specter and Rep. Joe Sestak, D-Pa. But the White House has opted to show its support for Specter, a longtime Republican who switched parties this spring, partly to avoid a likely loss in the GOP primary.
