According to Wikipedia, a Republican presidential primary debate was supposed to be held in Des Moines, Iowa in December 27 2011 in the context of the 2012 Republican presidential primaries. This debate was supposed to be sponsored by Newsmax Media and broadcast on Ion Television and was scheduled to be moderated by you know who?
DONALD TRUMP.
But this debate was cancelled.
But let's imagine : if that debate was not cancelled, what kind of questions Donald Trump would have asked to Mitt Romney, Newt Gingrich, Rick Santorum, Ron Paul, Jon Huntsman, Rick Perry and Michelle Bachman?
