In this Nov. 12, 2018 photo, Carolyn Bourdeaux, Democratic Nominee for Georgia's 7th Congressional District, displays a Gwinnett County absentee ballot as she speaks during a press conference outside of the Gwinnett County Board of Voter Registration and Elections in Lawrenceville, Ga. Bourdeaux was the top vote-getter for her party, but fell short of a majority in the state's primary election on Tuesday, June 9, 2020.. She'll face state Rep. Brenda Lopez Romero in a runoff. If Bourdeaux wins, she'll get another shot at the seat in parts of Gwinnett and Forsyth counties after she lost to Woodall by fewer than 500 votes in 2018.
