She is staying in the race in case Trump gets assassinated. That is the only way she would win. And she is the only competitor remaining.
The convention does not work like that.
If she stays all the way to the convention she will have at most a couple hundred delegates—10% of the total.
The other 90% of the delegates will pick someone else—and they will be a conservative—could be even be a member of the Trump family.
I agree. If they kill Trump it would most certainly be a defining moment in this countries history. The deep state won’t do it for that reason, their hopes are somehow he gets put in jail.
