Probably so.
If Trump earns the GOP nomination, he will lose the general.
If Trump doesn't earn the GOP nomination, he will run a third party campaign ensuring the Democrats win. The GOP nominee will likely see their political future go down in flames as well.
And GOPe will still be in place. Probably get stuck with Liz Cheney, and I will vote for the Rat over her.
Can’t beat ‘em. Our neighbor from Connecticut just told my husband he considers himself “purple” (purple is the new yellow) and Donald Trump runs the NY mob.
