One thing I wonder about is whether "not being Trump" is enough to attract enough swayable voters in the midwest. I figure to win, Trump has to carry FL and OH and the rest, so it comes down, again, to the midwestern states, WI/MI/PA/MN. And I think it will be close, 50-50 basically.
I think, personally, Biden needs to focus on "Three Things" he would do as President. Hillary offered a to do list that was too long, and unfocussed. I think the three things concept is useful and communicative.
And they should be affirmative things, not just "I'm not Trump".
It is ironic, to me, that my Number One concern for the country is the deficit/debt, and neither party wants to go there.
