Collins in ME can pull through even if Trump loses the state.
I think for others, AZ, NC, MI, Trump needs to pull them across the finish line.
Maine splits it’s four electoral votes.
In 2016, Trump won CD 2....80% of the state...by 10 points, and received one electoral vote. A repeat is quite possible. Hilarity won CD 1....close to Boston and more liberal than CD 2. One electoral vote for Satan’s daughter. Statewide, the Hildebeast won by 2.9%, giving her two more electoral votes.
I would be stunned if Collins loses. She’s good on local issues, and won 67% of the vote in 2014.
