Voters will cast ballots in a key U.S. Senate race.


Polls are closed in Maine where voters are weighing in on a key U.S. Senate race between Democrat Troy Jackson and incumbent GOP Sen. Susan Collins, who is seeking a sixth term.
The Senate race was upended earlier this year when the original Democratic candidate, Graham Platner, dropped out of the race due to allegations of sexual assault.
The state also has races for House seats and governor.
