A quote from the article "Jesse Benton, (Ron) Paul's national campaign chairman, said, "the selection of a reality television personality to host a presidential debate that voters nationwide will be watching is beneath the office of the Presidency and flies in the face of that office's history and dignity." Aah stupid, your Congressman is not the president.
Currently the only two republican candidates that have sent a positive response are Rick Santorum and Newt (not conservative enough) Gingrich. Rick "the stumbler" Perry and Michelle "miss speak" Bachman are undecided.
The former Utah Governor Jon (<2%) Huntsman who called the idea of a Trump-moderated debate "a joke," commented that he was "not going to kiss [Trump's] ring, and I'm not going to kiss any other part of his anatomy." Really Mr Huntsman, you need all the exposure you can get no matter how big that state tax cut was.
Mitt, stiff as a starched collar, Romney declined to participate. Why? If you never get above 20 something % can he win the nomination?
In reality if all politics are perception it makes sense to get all the exposure on TV for free that one can. Even if ION TV has a .5 share at any given time, the only cost is getting to Vegas and a place to stay.
