Obama has kept 45% of his campaign promises in his first term, according to the fact-checkers at Politifact. He's broken 22% of his promises, and compromised on 24%.
Obama has ended the Iraq war, ended torture, introduced new financial regulations, and signed healthcare reform, says Politifact.
He's failed to close Guantanamo, to restrict revolving-door lobbyists, and to bring Republicans and Democrats together.
The Washington Post gives Obama a much lower score on campaign pledges kept - they claim he's achieved only 2 out of 12 major campaign promises - ending the Iraq war and bringing diversity to the Supreme Court.
WaPo gives Obama partial credit for some other major pledges: financial reform, healthcare reform, improving US standing overseas, making government more transparent, and ending the Afghan war. (Some would quibble with whether Obama has even "partially achieved" the last few objectives.) And WaPo gives the POTUS a fail grade on the economy and Guantanamo.
