Digging into the crosstabs, the news gets even worse for Trump...
Republican Democratic Independent
Donald Trump 96% 5% 39%
Joe Biden 3% 89% 48%
Undecided 1% 6% 13%
... As you can see, Trump already had 96% of republican support. No room to grow there essentially. Meanwhile, 6% of Democrats are undecided. If we give them to Biden, he is already at 48% (AKA almost what Abrams got).
One thing that Trump had against Hillary in 2016 that he's likely not going to have against Biden is the support of independents. This is why I am little more optimistic about Joe's polling leads over Trump.
