The Way Forward

1) No.
2) Maine assuming Collins does not run, Alaska if Murkowski does run but not on the R ticket. Stretch would be NC (tillis).
3) Jon Ossoff is highly endangered (under 50% likelyhood of reelection IMO). Peters in MI is safer but still in danger. Stretch would be VA if Warner does not run.
4) The only states I would put money into on 'offence' is Maine and NC. I would save the bulk of the money for defense but if funds are thin cuff off Ossoff.

This is as of today. If President Trumps action cause (further) chaos and the public turns on him by 2026 then the map obviously expands for D senate pickups.

This also assumes there will be midterms .....
