Push him 3rd party and they lose.
The subject has been openly discussed in the U.S. Senate, at least since 1919, and the debate over Wilson's League of Nations.
If the GOP loses, the GOPe still retains its power. Keeping that power is paramount.
Further, I believe if a President Trump gets a look at the criminal files the NSA has on many in the GOPe as well as the Rats, he will have the Justice Dept. indict the lot of them.
If Trump were to expose but a small fraction of the corruption & collusion to the American people the Republican Party would collapse, & the Democratic Party would be known hence fore as the Communist Party USA.
Everyone above the rank of dog catcher in Washington, DC is terrified that an “outsider”, a non-politician, non-leech might expose them for the corruptocrats they truly are.
Maybe it is too late. Maybe the elites so control the system that can steal the election. You can bet they will try if Trump is elected. If they can’t now, it will happen soon & forevermore.
Maybe Trump is a total liar. Why? The guy could buy a country if he wanted to be king. Why lie your way into the Presidency only to then be attacked from BOTH parties, the media, & those that voted you into office, plus everybody else. Without a supportive GOP, Trump could easily be impeached for any corruption in office.
We know the GOPe is a bunch of liars for sure. We also know that if we have another weak President, if we have a President easily manipulated by the rich & powerful, the “land of the free & the home of the brave” will be no more.
