I'm going to start doing weekly (-ish) ratings.
Left and right arrows indicate a rating change to the left or to the right.
In the last week (or two-ish), I would:
Move AZ to Likely D. The AZ-08 numbers cement this.
Move TX to Likely R. I don't think Beto's going to happen. The primary numbers show that Texas, at the very least, doesn't seem to have the same enthusiasm for him as other states do for Dems.
Move PA to Safe D. While this is probably a conrroversial move, combining Casey's popularity, Lamb's win in PA-18, the ineptitude of Casey's opponents and their lack of traction in the polls, and the national environment, I'm pretty confident Casey won't lose.
Move MO to Lean D. I honestly don't think this move will last, but with Hawley getting caught up in the Greitens palooza, I'm giving Claire the slight edge.
Move TN to Tossup. Polling shows Bredesen performing quite strongly.
Move MS-Special to Lean R. Hyde-Smith seems stronger than expected, and McDaniel weaker. Also there's no second strong Dem to create the D vs D scenario, but there are other, weaker Dems who could bring about a Hyde-Smith - McDaniel runoff.
I'm also close to putting MT-Sen at Lean just out of caution.
