In a special election that is capturing the nation’s America’s political attention and even has the White House’s interest, a once-solid GOP congressional seat has now been rated a tossup.

On Monday, Roll Call revised its “Leaning Republican” rating in the special election to replace Tom Price in Atlanta’s 6th congressional district.

In an exclusive 11Alive poll, Democrat Jon Ossoff holds a commanding lead over the rest of the 18-person field. In the poll, Ossoff grabbed 43% of likely voters. Republicans Karen Handel (15%), Bob Gray (14%), and Dan Moody (7%) round out the top four. All other candidates combined make up 15%, and an additional 7% are undecided.

Right now, Ossoff polls below the 50% needed to avoid a runoff.

“Based on his position, the difficulty of accurately predicting special election turnout, the polls’ margins of error, and Ossoff’s financial advantage, we are changing the Inside Elections/Roll Call rating from Lean Republican to Toss-Up,” Roll Call said.

Price was named Donald Trump secretary for the Department of Health and Human Services, leaving a vacuum that will be filled through an April 18 special election and, if needed, a June 20 runoff. The race has national implications as both parties are scrambling to grab the seat.

Early voting continues in the race through Friday. Here are the latest early voting numbers from the Georgia Secretary of State:

  • Number of ballots cast: 14,811
  • Number of ballots voted in person: 12,331
  • Number of mail-in ballots returned: 2,480
  • Number of mail-in ballots outstanding: 6,145

The election is being held to replace Price, now President Donald Trump's secretary of Health and Human Services.

The district includes portions of Atlanta, Brookhaven, Chamblee, Dunwoody, Doraville, Tucker, Sandy Springs, Roswell, Alpharetta, Johns Creek Milton and Mountain Park. Before it was last redrawn as part of Census reapportionment, Republicans Newt Gingrich and Johnny Isakson held the seat.
