This is one of the areas this forum has completely deluded itself via becoming a near 100% leftwing anti-Trump echo chamber. There is MORE hard support of Trump this time but LESS soft support. That's why you have the "double haters" going to Biden but Trump's base views their vote overwhelmingly "for Trump" unlike 2016. Trump had more soft support than Hillary last time and that worked to his advantage. But this election has far less double haters, it is much more of a base turnout election than a lesser of two evils election. Trump has to exceed expectation when it comes to his base turnout and win a healthy majority of remaining undecided voters. That's how he wins. Biden wins by simply turning out Democrats like Obama did in '08 and '12 and he doesn't even need more independents/undecideds.
You are certainly one for projection aren’t you? No one here denies that Trump’s base is energized. The argument is that the 40-some odd percent of them is obviously not enough to win in a 2-way race with essentially no 3rd party votes this year.
