What debate? Remember, it never happened. As *everyone* refused to go. And it was in 2007......months before any primary.
Whereas Trump refused to go unless his demands were met mere days before the first caucus. Fox essentially told him to go fuck himself, and had the debate away. And Trump's opponents got superb TV time that Trump didn't get just before a crucial vote.
Trump employed his 'negotiating tactic' of walking away.....and lost. He got nothing from Fox, his opponents got free airtime, and Trump lost Iowa.
Its unlikely that Trump's 'negotiating tactic' of pouting and whining until he gets his way is going to be more effective with say, North Korea than it was with Fox.
