Are you guys on crack?
First of all, there is no chance Trump is not gonna win renomination so why would he consider such nonsense?
Second of all, educate yourself on what happens when there is a vote split.

I’m not a Republican but Trump has me voting straight R. Bush globalism was poison and I recognized it early on. If the party doesn’t stand with Trump and what his voters want, it will collapses. I’m not sure that resonates with ppl like you but nevertheless it’s the political reality Republicans face. Now go sell lock step unity to the Never Trump crowd.
