Something that hasn't been mentioned yet is that during the next reapportionment, a future congress could use Section 2 of the 14th Amendment to strip CDs (and EVs) from states like NC and TX that have been successfully sued for having voting laws that are too restrictive. They could penalize these states in the next reapportionment by the differential between turnout there vs. turnout in other states (perhaps compared to the states that have automatic voter registration and/or universal vote-by-mail?).
There is a 0% chance of this happening
