Montana goes to the polls Thursday to vote in a special election for the House seat vacated by Interior Secretary Ryan Zinke. On the ballot is Democrat Rob Quist, a folk singer, and Republican multimillionaire Greg Gianforte, who has consistently led the polls despite Quist's recent gains. The race, described by Gianforte as "closer than it should be," is an uncomfortable repeat for Republicans of close, but ultimately Republican-won, special elections in Kansas and Georgia.
