If by October the Trump agenda is still being blocked in Congress Trump himself should announce that he is calling for a Congress of concerned Americans to create the America Party (or what you will). Trump should begin preparing for that event by having people create the names of participants who are favorable to a change in the American political system. This should certainly put the coffin in the feckless Republican Party just as the Republican Party put an end to the feckless Whigs. The Third Party run could be expected to cause a split in the vote and lead to Congress being controlled by Democrats. If Trump could stand the heat for two years (and the man’s a rock), it would also lead to a landslide election of Trump’s America Party in 2020 and the revitalization of the United States.
The timing has never been better for such. He should’ve done it back when the GOP was pushing him to sign that crappy ‘loyalty’ contract.
