Senate approvals, from CBS/YouGov:
But they also polled the approval ratings of the Senators:
Michael Bennet (CO): +20 (60/40)
Ron Johnson: (WI) +2 (51/49)
Marco Rubio (FL): -12 (44/56)
Richard Burr (NC): -20 (40/60)
Johnson has been shown to be going down in most polls. I can't see what he is doing right all of a sudden. The approval rating for Bennett may be overstated, too.
Bennet is apparently out of danger. Rubio and Burr -- in trouble.
I can't imagine the Bennet and Johnson approvals being accurate. But Bennet should be safe. Literally, he Republicans keep blowing the Colorado Class 3 seat so hard it's not even funny. It's like they secretly don't want he seat. I also wasn't expecting Burr's ratings to be that low, either. I guess North Carolina doesn't Feel the Burr so much after all.
