Well I think we need to wait and see if someone has enough delegates after all the state elections first. First one to 1078 will be the nominee. Can’t really change the rules after they are made. If a person does not have enough delegates then a convention is the way to go.
Vote in the primaries so that none of them have the required number. These guys are for the birds.
The GOP needs a “hookered” convention so that we can see if they have any balls to confront the Democrats, or whether they are now political eunuchs.
Nope, not if you're a conservative. However, leftists have no problem changing the rules if they aren't getting the outcomes that they like. (Fla 2000)
