The latest 3 polls as I type this, pitting Joe Biden vs. Ron Desantis are:
Emerson: Biden leads by 6% (43%-37%)
Redfied & Wilton Strategies: Biden by 10% (47%-37%)
Ipsos: Biden by 8% (Biden 38%, Desantis 30%)

The sudden absolute disintegration of Ron Desantis may be due to:
Trump making him unpopular by making his supporters hate Desantis, and
Desantis signing a horrible extremist 6-week abortion law.
Being more electable than Trump was the only thing Desantis had going on for himself. Now he doesn't even have that.
