I would put Romney up there, but really, that isnt my first choice, and I don't know his platforms that well.  Now my golden choice probably won't win, mostly due to the '08 election, so I think Michelle Bachmann would be my main choice (I probably spelled the name wrong, sorry). 

To be honest, I think the republicans are playing a game.  Huckabee and Trump left, I think mostly to bring in attention, and with Sarah Palin's high negatives they probably wont run her.  I see Newt Gingrich running for the sole purpose of taking votes away from Ron Paul, and thats probably why they had this scandal recently, and then its going to come down to Mitt Romney and Michele Bachmann at the last minute.  Since the media was focusing on Trump, and now Mitt, Michele will actually look like a good candidate and win.  At least, thats what I think they are doing,  Its all a game, and I think the right wing is playing a media game against the left wing.

I could be wrong.
