With guest host Tina Fey back playing her famous doppelganger, this weekend’s "Saturday Night Live" portrayed the debate that wasn’t this week – featuring not just Sarah Palin but also would-be White House hopeful Donald Trump.

The faux Fox News debate also pitted Mitt Romney, Newt Gingrich and Michele Bachmann in the “GOP 2012 Undeclared Candidates Debate,” adding 2010 New York governor candidate Jimmy McMillan of the Rent is Too Damn High party for good measure.

The sketch represented one of the first attempts by the comedy show to spoof the 2012 presidential campaign. It followed a real debate Thursday night featuring a B-cast of declared Republican candidates, including former Minnesota Gov. Tim Pawlenty, Texas Rep. Ron Paul and former Pennsylvania Sen. Rick Santorum.

This second debate was introduced as featuring the “candidates you wish you knew less about.”
