I agree with you. And even the fake polls are going to have to change, sooner or later.
Steve Turley on YouTube did an analysis of Florida early voting. Without going into details, he is seeing Florida voting, so far, off the charts for Trump. And that is with counting every early dem vote as a Biden vote, which is not true. We know something like 20% or more of dems are going to vote for Trump (or at least not vote Biden). While Trump has 94% Republican support (never-trumpers not withstanding).
You mention the spontaneous car and boat rallies. In addition there was a spontaneous Amish Buggy rally and a spontaneous Trump car rally in .... wait for it .... Jerusalem!
Yet, we are told, Sleepy Joe, (Quid pro Joe), with no significant rallies, no enthusiasm and an agenda to turn America into Venezuala II is somehow way, way, way ahead. Hard to believe.
