It’s hard to find positive indicators regarding Trump’s reelection chances, but voter enthusiasm is one of them:
Most Trump voters are “enthusiastic” about backing the president while a plurality of Biden voters are merely “satisfied, but not enthusiastic” about the former vice president. And while only a handful of Trump voters, 6%, are dissatisfied or upset with him, some 16% of Biden backers feel that way about their guy. These are presumably Sanders voters who feel inclined to “vote blue no matter who”, but just barely. A meaningful ‘stimulus’ payment or promise of universal healthcare wouldn’t only dissuade many from voting, it would flip some to the president.
