well, Gingrich's personal life has been messy to say the least but I think that is behind him now....hopefully the GOP can rally behind Gingrich instead of splintering into little factions, the last thing we need is multiple candidates vying for votes (think Ross Perot).
I would not be surprised at all if Santorum drops out soon, he has been struggling lately.
I don't think Ross Perot is a good name to use when when talking about what we don't need. He predicted dang near everything that has went bad sense an he spent a fortune trying to warn us.
