Georgia’s Senate race on Tuesday continues to hang in the balance, as Republican Sen. David Perdue and Democratic challenger Jon Ossoff await results. The race could result in a runoff.

As of 2:59 a.m. ET on Wednesday, Perdue leads 51.0%-46.7. However, many Democrat-leaning areas are still counting votes. Metro Atlanta counties lean Democratic and have fully reported.

The race has drawn national attention, as Democrats sought to make gains after a tight gubernatorial election defeat in 2018. Democrats have been optimistic about their chances in 2020 after Georgia had long been a Republican stronghold.

Perdue, a 70-year-old businessman, entered the Senate in January 2015, after the resignation of former senator Johnny Isakson. A staunch Trump ally, he has supported the Trump tax cuts and the repeal of the Affordable Care Act.

Ossoff, a 33-year-old former investigative journalist and media executive, supports a public health insurance option and tougher regulations on Wall Street.

The race has seen multiple controversies. The Perdue campaign ran a Facebook ad showing Ossoff, who is Jewish, with a larger nose, an anti-semitic stereotype. Perdue has also mocked the pronunciation of Democratic vice-presidential nominee Kamala Harris’ name and has been attacked for using his Senate position to make "perfectly timed" stock trades.
