To quote a friend who was involved in collegiate fencing when they would assess their opponent as being schlubby and not too hard to beat. "Just don't suck" and you should win.
Organizing, raising volunteers and motivating voters will all require a clear view of what Trump is and not complacency. But, fergoshsakes, the voters who voted against Trump in 2020 won't vote for him now. Biden has all the Haley voters who refuse to vote for Trump.
Having the massive advantage in money will also have an effect. I realize that the untraceable effects of Epoch Times newsletters telling the low-intelligence churchie types that Biden is the anti-Christ will have some impact. Biden will win few rural/white districts but he will destroy Trump in the vote rich suburbs unless he "sucks".
