Everyone could smell Romney’s phoniness a mile a way.
But okay, I’ll try to acknowledge that you are so terrified of Trump that you are willing to destroy the republican party with a convention fight.
If no one goes into the Convention with a majority of delegates, then, by definition, it will be a brokered convention, and candidates would need to seek delegates pledged to other candidates. Your position is that only one candidate with less thana majority of delegates should be allowed to seek support from other delegates, and anyone else that does it would be “destroying the party.” I would disagree with your position even if your preferred candidate wasn’t a liberal Democrat pretending to be a Republican.
