Maine could be a dark horse.
I don’t think it will be, but there is an argument to be made for it being potentially a swing state.
Certainly an unlikely swing state, but NE certainly is pretty safe Biden, more so than ME.
So, the only good reason to campaign in either is because of the swing districts.
The point of the link of course is that a few electoral votes could swing the election.
(moot point if the election isn't close)
What I am wondering is if targeting TX is unwise since the money might better be spent
in firewall states if not also in less important states like the four in the link.
I would call targeting TX a gambit, but possibly a bad one.
