If Trump should run as a third party we must remember that a vote for Bush is a vote for Hillary.
If Trump bolts for a 3rd party, I’ll put on my metal colander helmet and join the conspiracy theorists who have been claiming Trump was a Hillary plant all along.
Seriously, if he does that it’s proof he was just playing the system of the GOP primary process to rig a Hillary presidency. I will not be emotionally crushed if that happens, it will be more of a feeling of resignation. I’m too old, too cynical, and too jaded to be either surprised or upset. In that event, Trump will turn out to be just another lying crook using the political system to rip off decent Americans. It won’t make him different in kind to what we already have as a ruling class, just different to a degree.
