Well, there are literally three towns left to report fully: Waterford, Westbrook, and Enfield. The first two have not reported anything yet, but Enfield currently has Courtney winning. Seems to me it’ll be up to first Enfield (with Courtney seemingly poised to win it), and next Westbrook.
Of course, even after all of this, there is the possibility that the losing candidate could contest the results. And, with 421 votes currently separating them, I would not blame either candidate for doing so.
In Senate news, Republican Bob Corker seems to be poised to beat Democrat Harold Ford, Jr., meaning the Democrats need to win all three remaining seats to control Congress completely.
