I think Trump should hold a rally, and call publicly for the end of the filibuster, once and for all. Keep rubbing the senators' collective noses in it, they'll come around, just as they did for Gorsuch.
It's a violation of the spirit of the Constitution, if not the written law of the land. The Constitution specifically states where supermajorities will be required in the conduct of Congressional business. Ordinary votes ain't one of 'em.
Get rid of it!
