Jon Ossoff, candidate for congress in Georgia's sixth congressional district, after speaking, poses for pictures with supporters and volunteers at the Sandy Springs Canvass Launch for Ossoff's final day on the campaign trail. Georgia voters steadily streamed into suburban Atlanta polling places Tuesday, June 20, 2017, set to decide the most expensive House race in U.S. history and put weeks of television ads, phone calls and ringing doorbells behind them. Either Republican Karen Handel will claim a seat that’s been in her party’s hands since 1979 or Democrat Ossoff will manage an upset that will rattle Washington ahead of the 2018 midterm elections.
