re: GOP to pick up 9 senate seats in November

I think that's optimistic, given that Republicans have been under-performing in every special election this year, apart from GA-06 where the Democrat was awful.

I think the GOP will lose the House, albeit not by colossal margins. But I think the Dems will pick up 35-45 seats.

In the Senate, the GOP will pick up WV and ND and either IN, MO, or MT. They'll lose AZ and NV. They'll hold TX and TN, though by uncomfortable margins. So they'll gain one seat.
