As if anything more has to be said about this guy at this point, I can't help but say a few things.
For one, this oft-mentioned Al Gore comparison is ludicrous. I'm fairly certain that if Gore was asked in October 2000 if he would fully accept the outcome of the upcoming election, he would've looked perplexed and said, "Why of course! I'm not sure why you're even asking that question...." Duh! No one knew Florida and hanging chads would soon become a huge issue, but that's not the point Donald! On principal, every presidential candidate must say pre-election that they will accept the election result, period. Done. Then, if in fact there is a close call, like 2000, you can contest and go through the process -- as Al Gore did. But that's post-election. Pre-election you clearly state you trust our electoral process and the result. You don't say it depends, or I'll let you know then, or I wish to leave you in suspense.
