HIstorically... the contested convention is rarely a good thing for anyone.... usually you wind up with a dark horse candidate winding up the nominee after lots of ballots.... Granted hasn’t been one in a long time, and haven’t had a major one in the primary era... but still historically a contested election doesn’t tend to favor the 1st or 2nd or even 3rd place folks on the first ballots.
If they do, I will Never Vote for Any Republican again.
