This is what was said in an interview with National Journal...
“Republican presidential candidate Herman Cain said on Thursday that he would definitely consider an invitation to run as the eventual nominee’s vice president, except if the nominee turns out to be Texas Gov. Rick Perry.
Cain, who rocketed to the top tier of the GOP field in several recent polls, was asked by reporters on the campaign trail for his thoughts on a hypothetical invitation to run as the eventual nominee’s No. 2.”
Here’s the entire article http://www.nationaljournal.com/2012-presidential-campaign/cain-says-he-would-not-be-comfortable-as-perry-s-running-mate-20111006
I can’t find where he said specifically he would be Mitt’s #2 but said he would be willing to be VP for ANY of the candidates except Perry. Seems like Cain wants to serve his country and will do it as #1 if Elected and would be willing to be #2 if invited.
That’s very different than ‘auditioning for VP’.
All the candiate up there would probably be avaiable for VP if they didn’t get the top slot.
