1. That's going to be a tough road-

But in a blue wave, anything is possible.

50 + presidency (meaning vice presidency, VP casts deciding vote in a tie) would be enough to get rid of McConnell as Maj. Leader.

2. 51 to 55 are a stretch

But I believe you missed the Maine Seat, and Susan Collins is beatable.
