I'm with the consensus -- Tonight I'm feeling about R+58 on my over/under. However, if this ended up around R+70, I wouldn't be surprised.
I wish I had the balls to make off-the-wall predictions
To do that one would have to spend a lot of time at it, to figure out which seats not that closely watched or polled, are in real play to flip based on money, ad quality, candidate quality, along with all the more generic polls, and other races, etc. Other than that, you are just a Charlie Cook etc, drone, or just take a shot from the hip. That was what I did when I came up with 50-60 a couple of months back - I just shot from the hip. To now try to jerk it up another 10 seats is just too arduous for this old man, and after I did all that work (to generate something I could really defend), I might not come up with anymore seats anyway, and what fun would that be?
It will be more fun to critique Sam and Vorlon, assuming they explain their calls of interest.
I explain every call, you know...
