Just in from Public Policy Polling:
New PPP polls find Sara Gideon leading Susan Collins 47-43 in the Maine Senate race and Mark Kelly leading Martha McSally 47-42 in the Arizona Senate race.
Additionally a PPP poll for a private client last week found Cal Cunningham leading Thom Tillis 46-41 in the North Carolina Senate race, and when PPP last polled the Colorado Senate race John Hickenlooper led Cory Gardner 51-38. This makes four Republican held US Senate seats where PPP has found Democratic challengers with at least a 4 point lead.
The Maine result is most interesting. When PPP first polled the Gideon-Collins match up for a private client last spring, Collins led by 18 points at 51-33. The reason for the 22 point shift since then is that in the wake of opposing impeachment, Collins has lost most of the crossover Democratic support she’s relied on for her success over the years.
Last April Collins had a 32% approval rating with Hillary Clinton voters, and trailed Gideon only 59-28 with them head to head. Now she has just a 9% approval rating with Clinton voters, and trails Gideon 81-10 with them head to head.
