Jon Stewart's last official day with "The Daily Show" will be August 6, but news of Donald Trump considering running for the republican nomination, is almost too tantalizing for the late-night host to walk away from.While Stewart has noted a few of the "very colorful characters" in the GOP presidential field before -- Rick Santorum (R-PA), George Pataki (R-NY), Lindsey Graham (R-SC) -- he conceded that, for him, there is only "one F*ckface von Clownstick.""The Daily Show" could fire its entire writing team if Trump ran; the jokes would practically write themselves.
