They saw him for what he was, and tried to prevent him from crashing their party. Lindsay Graham called him a kook, unfit for office. Ted Cruz said Trump lies all the time.
But they all fell in line when he beat them at their own game by winning over the voters that rightwing propaganda had been indoctrinating for decades. The groundwork had been laid for a reality show con man unconstrained by norms, boundaries, or actual reality.
The Republican establishment had its opportunity in the 2nd impeachment trial to rid itself of this vile creature once and for all. Those who still had a shred of fealty to the US Constitution were horrified by the violent insurrection incited by Trump. McConnell and McCarthy both blamed him for the assault and desecration of our nation's Capitol.
But they lacked the courage to hold him accountable -- because they would then be held accountable by their voters who believed the lies of a stolen election and were still enthralled by their orange idol.
This will be the last election for the orange shit stain whose foul odor hangs over all of our country. Either he will be rejected next week or will die in office.
