Doing a search reveals that Obama has sponsored 50 bills in the current Congress. McCain has sponsored 21. Notably:
McCain: "I want to again thank the bipartisanship that is associated with this bill, including Senator Carper and Senator Obama."
Bush: "I want to thank the bill sponsors, Tom Coburn from Oklahoma, Tom Carper from Delaware, and Barack Obama from Illinois."
