PPP calls the Maine polling "most interesting" due to a stunning turnaround from last spring when Collins was leading Gideon by 18 points, 51-33. Perhaps Collins is concerned. She should be. The dual Kavanaugh/Trump acquittal votes aren't turning out so hot with Democrats. "Last April Collins had a 32% approval rating with Hillary Clinton voters," PPP writes, "now she has just a 9% approval rating with Clinton voters." Collins' overall approval rating now is also 24 points underwater, 33%-57%. Sorry, not sorry.

Kelly's lead over McSally, however, hasn't changed much from last spring when he had a 4-point advantage of 46-42. McSally never won that seat to begin with: She was appointed to fill it after Sen. John McCain passed. Perhaps Arizona voters are suffering from buyer’s remorse on a purchase they didn’t even make.

PPP writes that the North Carolina data comes from a survey the outfit did for a private client last week, so no further information beyond the top lines were available. The Colorado data comes from a poll PPP conducted last year in the race between Gardner and Hickenlooper.
