The Downballot: Must-watch races on election night (transcript)

Election Day is finally here! Joining us on "The Downballot" this week to preview all the key contests is Daily Kos Elections editor Jeff Singer, who has the goods on races big and small. Singer kicks us off by getting us up to speed on the battles for governor in Kentucky and Mississippi, two conservative Southern states where it's Republicans who are acting worried. Then it's on to major fights in Pennsylvania, where a vacant state Supreme Court seat is in play, and Ohio, where an amendment to enshrine abortion rights into the state constitution is on the ballot.

Singer also highlights a pair of bellwether legislative districts in Virginia, where both chambers are up for grabs, and then it's on to some lesser-known—but still exceedingly important—races further down the ballot. Several are also taking place in swingy Pennsylvania, including a critical contest that will determine who controls election administration in a major county in the Philadelphia suburbs. Democrats will also be hoping for a bounce-back in the county executive's race in Long Island's Suffolk County, an area that swung hard to Republicans last year.
