John McCain Quote

[On presidential candidates not condemning the controversial MoveOn. org ad in The New York Times.] If you're not tough enough to repudiate a scurrilous, outrageous attack such as that, then I don't know how you're tough enough to be president of the United States.

As quoted in The Boston Globe (16 September 2007).
