You could be right but I don't see it. If you mean in the primarys maybe, but overall, Dems will vote Dems, Reps will vote Reps..
Winning will be mostly about turnout (who chooses to stay at home versus who has the passion to go to the polls) and also about Independents, of whom there are enough to make the margin of difference. Democrats voting Democrat and Republicans voting Republican may more or less cancel each other out. “NICE” and “TRUSTWORTHY” will be rewarded, as a reaction to the harshness and melodrama of you know who. But neither party necessarily has the edge on these characteristics, maybe the Democrats a bit.
