US TV networks project Raphael Warnock will become the first black senator for the southern state. The Democratic Party of US President-elect Joe Biden is on the verge of taking control of the Senate as results come in from two elections in Georgia. If the Democrats win both, Biden will have a much better chance of pushing through his legislative agenda. The election is being rerun because of Georgia’s rule that a candidate must take 50% of the vote in order to win, and with 98% of votes counted, US TV networks and the Associated Press news agency called the first of the two races for Warnock.
