fwiw I think it’s probably impossible to replace a vacant VP slot with a split Congress now, which creates some real bad incentives when the out-party holds the House
to be extremely clear about what I’m saying:
If Biden were to vacate office tomorrow, Harris would be President, VP would be open, and Speaker Johnson would be next in line.
The VP spot there can’t be filled without a majority of the same House that resulted in Speaker Johnson, and surely someone is going to notice that we’re a heartbeat away from a Republican President.
