Jebbie seems to be trying to tick off people he needs to get elected. Like he wants to flame out of the primaries.
Then he will lay back and not spend those millions, bank them and take a vacation, earning interest on it for his next campaign, and he'll maybe show up here and there for a debate where he will look and sound like the spineless jellyfish he is, and ultimately lose the election to either the Hildebeast or the First Wookie. If it starts to get close and look like he might win, well then, he'll just DROP OUT.
Sound familiar?
It's all part of the plan!
