Tuesday is the final day of voting in two very tight runoff elections in Georgia that will determine control of the U.S. Senate. Democrats Jon Ossoff and Rev. Raphael Warnock are challenging incumbent Republican Sens. David Perdue and Kelly Loeffler. Republicans and Democrats all the way up the food chain make a final push to turn out the votes. The outcome of the races will have huge ramifications for the incoming Biden Administration’s ability to pursue its policy goals.
