President
I think Sabato will be more cautious this year seeing how 2016 went, but ultimately his prediction will be a Biden win.
Senate
On the other hand, I see him making bold predictions with the senate, especially in Montana and Kansas and moving Alabama to a strong Republican shade of red.
I think the presidential map will look like that, maybe give or take NC, FL, and GA.
In the Senate, AL will be Likely R (since he almost never puts races with incumbents as Safe for the challenging party), NM will be Safe D, KS will be Lean R, and GA Special will be rated Leans Runoff like the 2018 governor's race was.
He (correctly) put PA-GOV 2014 as Safe D.
