Secret Plan? We’ve known about the “phone and pen” thing for about 15 years.
And Trump flat-out stated at one of his rallies that if we lose House and/or Senate he will veto everything so Congress has to negotiate with him. That’s called “checks and balances” and there’s nothing secret about it at all. In fact, it is the Founders’ way to have accountability. And that accountability - the thing that separates free nations from banana republics - is the reason that the DSA and their democrat caucus openly want to get rid of the Constitution, along with the Presidency, Supreme Court, Senate, borders, and jails.
That word “secret” doesn’t seem to mean what these people think it means.
