I have no idea what you're banging on about here or what you think my point is. By your own admission, Trump voters are either hard core MAGA heads or habitual high-propensity Republican voters: what is to be gained from trying to win them over when there are large swaths of the electorate (independent low-propensity voters) waiting to be tapped into?
I agree but you don't do that by lumping them all together and calling them names.
Like it or not 74 million people voted for Trump. Rather than calling them all morons you might want to ask why they are so disenchanted with the way Washington operates that they would vote for someone like Trump. At least as many independents lean toward Republican as lean Democrat, maybe more.
The Democrats flipped Georgia for the Senate and Whitehouse. Abrams and Biden didn't do that by calling Republican voters morons. The Dems had good candidates and ran a good campaign, the Republicans had crap candidates, ran a lousy campaign and in spite of Trump doing his best to sabotage them, it was still a lot closer than it should have been.
