NEWPORT NEWS — The balance of power in Virginia’s legislature turned on a single vote in a recount Tuesday that flipped a seat in the House of Delegates from Republican to Democrat, leaving control of the lower chamber evenly split. Democrat Shelly Simonds wins recount in legislative race over Republican David Yancey and resets politics in state capitol. The outcome, which reverberated across Virginia, ends 17 years of GOP control of the House and forces Republicans into a rare episode of power sharing with Democrats that will refashion the political landscape in Richmond.
