"You know, I said something to John about how one Democrat after another compared Obama to Lincoln. And John told me, 'Sarah, I knew Abraham Lincoln…[pause for laughter and cheers from the cooperative home-team crowd]…and Barack Obama is no Abraham Lincoln. [wait for gleeful roars to die down] By the way, I think it's important to say that I borrowed that line from Lloyd Bentsen -- I wouldn't want Joe Biden to accuse me of plagiarism."
