How can anyone force anyone else to support someone?
One way would be to have a state delegation chairman announce that all of a state's delegates cast their votes for Romney without actually giving those delegates an oppertunity to vote or asking them who they wish to vote for.
Another way is by witholding credentials until a delegate agrees to vote for Romney.
Further still you can just ignore no votes while a pre-programed teleprompter tells you how delegates voted.
