The race for Nomination is NOT over.
Even with the endless and ubiquitous CHEATING
by RINO Romney the Premier backstabber.
You’re right, the race is not over, but the remainder would have to be pretty much united behind somebody else and Gingrich and Santorum are both almost out of money.
For Gingrich, it is. He has won two primaries. I don't see him picking up any big slates of delegates in New York, New Jersey or California. Or even in Texas. In the unlikely event this goes to a brokered convention, I don't see the power brokers choosing someone who lost 48 states (and all of the territories).
