Shortly after Rep. Doug Collins announced he would run for U.S. Senate, a dozen people rushed to fill his space in District 9.

The Northeast Georgia district was created in 2011 during the reapportionment process, and Collins has been the only person to hold this seat.

Collin, running for a fourth term in 2018, won with nearly 80 percent of the vote. The district is considered a Republican stronghold.

However, the contest has still attracted three Democratic candidates in addition to nine Republicans.

Here’s who we’re watching:
