BLUE
Sara Gideon (ME) is building a lead and has momentum in the polls
Incumbent Gary Peters (MI) has a growing lead

TOSS-UPS
Theresa Greenfield (IA) and Cal Cunningham (NC) are in very tight races; Greenfield is gaining momentum and the polls in NC are staying in a tight window. Cunningham is maintaining a narrow lead.
Steve Bullock (MT) has a slight edge but the polling is limited.

LONGSHOTS THAT ARE POLLING WELL
Jaime Harrison (SC) and Amy McGrath (KY) are both polling well in deep Red states.
Barbara Bollier (KS) is polling well against Kobach but less well against other Republicans.
Jon Ossoff (GA) has shown well in a single poll against Perdue, but better polling is needed

IN DANGER
Doug Jones (AL) is lagging both Sessions / Tuberville in polling matches, but is within striking distance.

RACES TO WATCH
Al Gross (AK) may offer a real challenge to Sullivan, but there's no real polling on this race.
MJ Hegar may gain momentum in TX against Cornyn, who has soft support. No recent polling to know how viable this is.

If the election were held today, and the polls were correct, Democrats would win NINE seats and lose one. However, the election won't be held today, and the polls are not decisive. Nevertheless, the Democrats are very well positioned to flip a net of three seats, which will flip the Senate if Biden wins.
