Polls are of little help.
Quinnipiac has Sink leading 45-41.
Susquehanna has Scott leading 47-45.
Mason Dixon has Sink leading 46-43.
Rasmussen has Scott leading 48-45.
All of the polls suggest that - within their margin-of-error - this is an extremely tight race with neither Scott nor Sink certain of victory.
Crowley Political Report doesn't know who will win - but we're fairly certain it will be a fascinating election night.
