Voters in Georgia’s 6th Congressional District will vote Tuesday to fill the seat vacated by former Rep. Tom Price, a Republican who was tapped to become President Trump’s health and human services secretary.

The district has been a Republican stronghold for decades, but upstart Democrat Jon Ossoff is polling well with his strong anti-Trump message.

The race features 18 candidates - 11 Republicans, five Democrats and two independents.

To outright take the so-called “jungle primary,” the winner must get more than 50 percent of the vote. If not, the leader would face the second-place finisher in a runoff.

Ossoff, a 30-year-old former congressional staffer and documentary filmmaker, is expected to get the most votes but not the majority, likely sending him and one of the Republican candidates to the June 20 runoff.

On "America's Newsroom" today, Karl Rove said he is concerned that the district may go Democrat for the first time since Newt Gingrich won the congressional seat in 1978.

"It's a tough hill to climb, but there is a chance ... that the Democrat could win it, win 50 percent and avoid the runoff," Rove said.

He added that if the race does go to a runoff, then the question becomes: How well can the Republicans unify and come together behind one candidate?

"There could be real problems," Rove said, noting that last week Democrats came close to claiming open seat of Kansas' Mike Pompeo, who is the new Director of Central Intelligence Agency.
