Not all races are settled in the US midterms. Some remain too close to call, while others could be subject to challenge, including some critical battles in Florida and Georgia. CGTN's Nitza Soledad Perez has more.

In a nationwide election, count on swing state Florida to add extra drama. Democratic Senator Bill Nelson is calling for a recount in his reelection bid against the current Republican Governor Rick Scott.

Unofficial results show Scott leading the contest by less than half a percent. In Florida, that slim of an advantage triggers an automatic recount. Final numbers are expected by Saturday, and if necessary, the recount would follow.

In the race for Scott's governor's office, Democrat Andrew Gillum conceded a narrow defeat to Republican Ron DeSantis.

ANDREW GILLUM FLORIDA DEMOCRATIC CANDIDATE FOR GOVERNOR "I sincerely regret that I couldn't bring it home for you. But I can guarantee you this, I'm not going anywhere."

Ron DeSantis celebrated his triumph and thanked his political mentor, Donald Trump.

RON DESANTIS FLORIDA REPUBLICAN CANDIDATE FOR GOVERNOR "I'd like to thank our president for standing by me. When it wasn't necessarily the smartest thing to do. Mr. President I look forward to working with you."

But even this victory could be subject to a recount if the final tally slips DeSantis's lead to under the half percent line. The former congressman and navy veteran ran a conservative campaign echoing many of the President's positions: He's for cutting taxes, building a border wall and isn't sure climate change is real.

A few miles north, another candidate is not giving up. Democratic contender for the governorship of Georgia, Stacey Abrams, refused to concede.

STACEY ABRAMS DEMOCRATIC GEORGIA GOVERNOR CANDIDATE "But I'm here tonight to tell you votes remain to be counted. There are voices that are waiting to be heard. Across our state, folks are opening up the dreams of voters in absentee ballots and we believe our chance for a stronger Georgia is just within reach."

Her Republican rival Brian Kemp currently leads by just a hair over 50 percent of the vote.

NITZA SOLEDAD PEREZ TAMPA, FLORIDA "That means that Kemp could possibly fall BELOW the 50 percent mark once all absentee and provision ballots are counted. Should that happen, a runoff between Kemp and Abrams would be held in December. The odds of winning in such a scenario remain long, but as of now, Abrams is not ready to give up on her chance to become the United States' first female black governor. NSP CGTN TAMPA, FLORIDA."
