I absolutely agree with that. The obvious problem with a 3rd party run is the US Constitution and the state-by-state denial of access to having a candidate appear on a ballot. The only 3rd party currently with almost all states (48, I think) is the Libertarian Party.
Trump doesn’t need to run third party. He is destroying the field NOW in the a Republican party. Based on this policy paper, he is only going to get more backing. He will probably get hoards of Democrat cross overs in the open primary states.
Blue Collar Democrats are as sick of the Leftist politicians giving all the jobs and benefits to foreigners as well. They want a strong America too.
