One of the greatest chairmen the Democratic Party ever had, Bob Strauss ― (cheers, applause) ― used to say that every politician wants every voter to believe he was born in a log cabin he built himself. (Laughter, applause.)

Because nobody's right all the time, and a broken clock is right twice a day. (Cheers, applause.)

... in Tampa ― did y'all watch their convention?    I did. (Laughter.)    In Tampa, the Republican argument against the president's re-election was actually pretty simple ― pretty snappy. It went something like this: We left him a total mess. He hasn't cleaned it up fast enough. So fire him and put us back in. (Laughter, applause.)
