When the Republican Presidential nomination comes around, it'll be the voters/the Republican masses that'll decide ultimately if Trump goes away, not television talking heads. Outside of actually agreeing with him, I'm under the assumption 90% of Republicans currently in office still show Trump support because the Republican masses still give him support.

I wonder if establishment talking head Republicans trying to kick dirt on Trump will perversely result to right leaning folks to support him more.

All the above is assuming of course the man isn't behind bars, which I pessimistically think is a long shot, but I suppose time will tell.
