Other than the choice of the Supremes, and the bonus of not Trump, wondering quite how much difference a Biden presidency will make.
It seems to rest on 2 things to me. First, the relationship with China, and I can't see a good solution there that supports the rights of those in Hong Kong and the Uighurs without getting locked in a global financial conflict.
Second the ongoing social split in America, where even if Biden is seen to be able to reconcile those currently protesting with some of the centre risks effectively causing a further boost to those on the more outre parts of the right.
Both issues feel like squaring of circles.
Add to that the ongoing discussion of whether he might pick Mitt Romney as his VP.
