The task won't be easy. An Atlanta Journal-Constitution analysis showed Democrats would need to erase significant gaps with Republicans in a sweep of conservative-leaning seats to take control of the chamber.

Democrats are targeting the 16 seats where a Republican won with less than 58% of the vote last year. In addition, Democrats couldn't afford to lose many of the 11 House seats they picked up last year, including some in districts long represented by conservatives.

It's the second initiative aiming to give Democrats control of the chamber. The Georgia House Majority Project launched in June with the goal of targeting the most vulnerable Republican incumbents – mostly in the close-in suburbs – with digital ads and direct mail.

The stakes are high. The party that controls the House in 2020 will have great influence in redrawing district lines the following year, and will help set the agenda on Georgia's most divisive and pivotal political issues.
