Im assuming Doug Jones is one of them, and the dude from Michigan is another.
The gal from AZ, which is safe for Trump.
If Jones internals show he has a chance of re-election the could lose him because he knows hes dead if votes to convict. Manchin just re-elected so its hard to say. The Mi Dude is up in 20 and in very close race but I would be shocked if he broke ranks and Senema is out in space so who knows.
