Why bother with the voters. Keep them out of the inner circle.
It would be absolutely time to start a 3rd party if the republican party disenfranchises their loyalists. It may be too late for this round but could very well be in place for the 2018 mid-terms and 2020 elections.
I would support trump as a third party candidate. I think it could work. Remember Connecticut and Joe Lieberman. The dems thought they could screw Joe but he ended up screwing the dems. I think trump could easily screw the GOPe.
