Nope, 3rd party splits the useless republican party which will guarantee a democrat majority, cheating or not.
That seems sort correct-ish.
But in the moment, we have RINOs a plenty aligned with Democrats on many things.
A "useless" Republican Party -- please note the equivalency -- is a useless Republican Party.
A disruption in either party would be welcome, to my view. Trump and RFK Jr rising to actual candidacy would cause many, many heads to explode. And the bureaucratic, deep state to act out, I would think, in ways as yet not seen.
