Mitt Romney has announced that he won't participate in the GOP version of the YouTube debate, stating that "I think the presidency ought to be held at a higher level than having to answer questions from a snowman," Guliani is just overscheduled.
Both of them are lame. No one gets to be a national presidential candidate without a lot of campaigns that involved kissing babies, riding on ponies, (in Rudy's case, dressing in drag) and doing a lot of other things that many people might view as 'beneath their dignity'.
The American people don't all wear $2,000 suits and carry briefing books. That doesn't mean a presidential candidate can duck their questions.
This is a B.S. decision that will cost both of them - and should. If they can't answer unplanned - and sometimes off-the-wall - questions from the people who they want to vote for them, they don't deserve the office.
