Who will be the RNC's 'mystery speaker'?

The Thursday evening speaker line-up has a small hole in it, leaving many followers of the Republican National Convention wondering who might fill that slot...

"I think everyone's going to have to tune in on Thursday night and check it out," RNC chairman Reince Priebus told Fox News Tuesday morning. "It's going to be a great night."

I know who I would and would not like to see speak on Thursday night (::cough, cough:: ANYONE BUT TRUMP!), but I'm especially curious who readers of TheBlaze would like to hear from.

So, what do you think -- will it be Sarah Palin? Gen. David Petraeus? Ted Nugent? Clint Eastwood?

Tell us who your pick would be to fill this mystery speaking slot!
