Who should Romney pick for Vice-President?

So, Dick Cheney thinks Palin was a bad choice because she wasn’t qualified to be President.  Well, she was more qualified than Obama, having at least served as head of an executive branch before.  In any case, the time is almost upon us for Romney to pick his VP candidate.

Who should he pick?  Who will he pick?  Cheney also said that there were two lists, a long list of people who need to be on the list for political reasons and a much shorter list of seriously considered candidates.  Do you think your favorite candidate is on the long list or the short list?
