We are obviously still waiting to know about LOTS of races, but if Democrats win the White House but lose control of the Senate, we could be in for a whole lot of deadlock. Rep. Alexandria Ocasio-Cortez's former chief of staff voices some of those worries here. I spoke to Chakrabarti and other Democrats a couple of weeks ago about about what a Democratic-controlled White House, Senate and House might look like. Probably a lot of expectations-shifting going on in Senate-watching circles this afternoon.
