Well it seems Romney has the nomination all wrapped up now. Though Paul and Gingrich will probably hang on as spoilers until the convention. Paul to help hand over the Looneytarian reins to his boy Rand, and Gingrich just being Gingrich.
But boy oh boy, do the 2010 (Right-wing Tea Party) and 2012 (moderate Republican against a 2nd term Democrat) elections look just like 1994 (Right-wing Contract with America) and 1996 (Moderate Bob Dole).
