Not true. 19 states with almost 1,000 delegates have left to vote. Romney isn't even close to having the 1,144 delegates he needs. He needs about half of the upcoming ones. He's the weakest frontrunner in at least 35 years. This has been an unprecedented primary in many ways, starting when 3 different candidates won the first 3 states. If the voters in the next 19 states don't want Romney, they have the power to choose a brokered convention.
Okie dokie. You keep believing that. Eventually reality will hit you, but I know some people aren't ready to face it yet.
