“Is Cornyn’s primary the first one?”
Yup. March 4th, with early voting starting this coming Tuesday. We can get the ball rolling and build momentum.
If Cornyn is forced into a runoff, we can remove McConnell and Cornyn in May, Graham and Cochran in June, and Alexander and Roberts in August.
I do think if we forced Cornyn into a runoff, the momentum would grow significantly for the challengers in other races.
