Among voters in each state
Sara Gideon (D) over Sen. Susan Collins (R): +4 (47-43)
COMMENT: This is the fourth poll in a row showing Democrat Gideon leading incumbent Collins by 4-5 points. Handicappers rate the race a tossup.
Sen. Lindsey Graham (R) and Jaime Harrison (D): even (44-44)
COMMENT: This poll has incumbent Graham tied with his challenger. It should be mentioned that the poll was conducted by Quinnipiac, which often shows Democrats doing better than do other polls…. Despite recent polling that shows a close contest, handicappers still rate the race likely Republican; they’re surmising, and reasonably so, that the state’s conservative orientation will save Graham in the end. Nonetheless, this is one to watch. If Democrats upset Graham, it would mean a really big anti-Trump wave across the nation.
Sen. Mitch McConnell (R) over Amy McGrath (D): +5 (49-44)
RON’S COMMENT: McConnell leads all general election polling we’ve seen, but this Quinnipiac survey is the closest. As mentioned, Quinnipiac often shows Democrats doing better than other polls…. Handicappers rate the contest likely or safe Republican.
