I give the Slimes a pass on this one. If the guy on the right in the light blue shirt with the tie is Bush, he is not near enough to Obama that both could have been recognized in one small photo of the crowd.
The article does state that Bush and other Republicans were present:
Joining Mr. Obama on Saturday was former President George W. Bush, who signed the reauthorization of the Voting Rights Act in 2006, as well as more than 100 members of Congress. About two dozen of them were Republicans, including the House majority leader, Kevin McCarthy of California. While sitting onstage, Mr. Bush made no remarks, but rose to his feet to applaud Mr. Obama, and the two men hugged afterward.
