BREAKING: Trump-endorsed candidate Clayton Fuller wins Georgia congressional election to replace MTG

Republican congressional candidate Clayton Fuller, who was endorsed by President Donald Trump in the lead up to a special election in Georgia to fill Marjorie Taylor Greene's vacant seat, has won the election against Democrat Shawn Harris.

The Fuller was determined to win the election by Decision Desk just after 8 pm eastern time with around 40 percent of the votes in. The runoff election comes after Greene resigned from Congress on January 5 this year after she went from ally to outright attacking Trump.

Her resigning from Congress sparked the special election. Harris and Fuller were forced into a runoff election in March after there was a crowded field of candidates vying for the position. Fuller will be up for re-election in the midterms like the rest of the House members in Congress.

The win for Fuller is needed for the GOP to give a little bit more cushion to the razor-thin majority the party has in Congress. House Republicans currently have a 217 to 214 margin. After Fuller is sworn in as a lawmaker, the GOP will be able to afford two "no" votes from the party block instead of just one.

Greene's district had backed the president by 37 points. With 60 percent of the votes in, Fuller had 40,191 votes, and Harris had 31,480. The two political parties have been watching Georgia as well as other special elections as bellwethers as they look forward to the midterm elections.

During the initial primary Harris had won first with 37 percent support and Fuller got second at 35 percent support.
