I favor just letting things play out. A vote has yet to be cast. The candidates will have their mettle tested including their organizational and fund raising skills. Hopefully, we will have a primary like the Dems had last time in 2008 between Hillary and Obama. It kept the candidates in the public eye including their attacks on Bush well into the Summer and it forced both camps to run in every state including setting up their organizations, which were used during the general election.
One thing I won't do is to accept the proposition that there are only two choices--Romney or Gingrich. Maybe we can get lucky and have a brokered convention.
