This week’s adjustment by Cook is not that extensive, but it’s a doozy:

Those are all formerly-safe races that are now abruptly… not-safe. They’ve all gone from Safe Democratic to Likely Democratic, but this kind of movement is consistent with a continuing drift towards the GOP side.  It would be interesting to see what the Toss-Up and Lean Republican totals would look like right now if Cook was less conservative about assigning incumbents to the latter.  Also: look at some of those names.  There are some heavy hitters on the Democratic side on that list, and they’re even now being told the bad news.  Will a week be enough time to topple them?

I don’t know.  Let’s find out.
