No, I think they don’t want the party split which would ensure a DEM victory - and it would. Trump said he wouldn’t run 3rd party if they treat him well. However, he never outlined what that entailed. I don’t perceive it as knuckling under to the establishment. I see it as the establishment embracing him as a legitimate candidate. If he does sign it - then those who get their panties in a was over it have the wrong agenda. We want Trump to win, but, he can’t always be a lone wolf.
“I see it as the establishment embracing him as a legitimate candidate.”
Absolutely not.
The more I think on it the more I think this is mainly to demean him with anti-establishment voters.
But of course, I don’t have inside knowledge of what’s going through their little twisted minds.
