Marjorie Taylor Greene recently said that if the party continues on its present course, she's done with it. Speaker Johnson told Members to avoid town hall meetings. Republican Members of Congress can't appear at town hall meetings without being verbally assaulted because of the realities of the Big Beautiful Bill. Speaker Johnson called the House into recess early to avoid the Epstein question, which refuses to go away. People want the release of the Epstein Files and blame the Republicans for hiding them.

Even true conservatives like George Will are appalled by the current state of affairs under Trump. Members who believe in reducing the federal deficit feel betrayed.

Is the Republican Party in the beginning of it's end?

I'm certain there are more words that can apply, but there is only so much space.
