The Republicans take their turn answering unpredictable YouTube questions on September 17 in St. Petersburg, FL. When the the debate was announced by the state party, CNN and YouTube last Friday, Sen. John McCain immediately RSVP'd. Since then, silence from the other campaigns.
Mitt Romney didn't like some of the more frivolous trappings and told the New Hampshire Union Leader that "I think the presidency ought to be held at a higher level than having to answer questions from a snowman."
Several campaigns report receiving a formal invitation today.
