ROSWELL, Ga. (AP) - The most expensive House race in U.S. history heads to voters Tuesday in suburban Atlanta.
Either Republican Karen Handel will claim a seat that's been in her party's hands since 1979 or Democrat Jon Ossoff will manage an upset that will rattle Washington ahead of the 2018 midterm elections.
Their matchup in Georgia's 6th Congressional District has become a proxy for the national political atmosphere and a test of GOP strength early in Donald Trump's presidency.
Ossoff led an April primary but fell just short of an outright victory, sending an already costly race into a two-month runoff campaign.
Trump barely won the district in November, giving Democrats an opening once Republican Tom Price resigned the seat to join the president's Cabinet as health secretary.
