The Club for Growth is investing $10 million in Georgia to preserve the Republican Party’s Senate majority, with plans to boost GOP candidates in two Jan. 5 runoff elections that will determine the balance of power on Capitol Hill for the next two years.

Besides spending $10 million or more on a robust advertising campaign, the Club for Growth is collaborating with five conservative groups and about one dozen Republican senators and senators-elect to push Sen. David Purdue past Democratic challenger Jon Ossoff and help Sen. Kelly Loeffler hold off Democratic challenger Raphael Warnock. With presumptive President-elect Joe Biden poised to take the White House on Jan. 20, Senate Republicans can afford to lose just one of the two Georgia seats and still retain their majority.
