That website is great for Congressional seats.
The date was Sept 28 - before the Kavanaugh debacle.
Hopefully that changed some of their predictions which as of 9/28/18 are these:
Republicans have a 240-195 majority. Democrats need a net gain of 23 seats for a majority. Most likely outcome: Democratic gain of 25-35 seats, with larger gains possible.
I don’t pay much attention to the predictions. But it identifies competitive seats. In all these years, the safe seats are always won by favorite. Only one I remember when it was an upset. First time Shea won nh-1.
Ct-5 is interesting
But Gop is defending seats, not trying for pickups.
