I wouldn't go that far. They have a tough path but we have a lot of seats to defend. Jones is the only seat we have a high probability of flipping. They don't have any 'easy' flips, but Republicans Gardner, Collins, McSally and Tillis are definitely in play. If they flip all four of those, they probably take the WH too. In the unlikely event we retain all 23 seats we are defending and flip AL, it's going to be an epic night.
So far, I don't see the GOP spending much money in states we might be able to flip, but that should change biggly after their primaries. At this point, conservatives need to quit applying purity tests, and work on retaining or increasing our majority.
