The numerous Georgia suits challenging the Nov. 3 presidential election results have been grabbing headlines, but behind the scenes, the four campaigns in the two upcoming Senate runoffs have retained well-known political law firms to advise on compliance and other issues.

As early voting started Monday for the two Senate runoff races, the campaigns for Republican Sens. David Perdue and Kelly Loeffler, as well as Democratic challengers Jon Ossoff and Rev. Raphael Warnock have kicked into high gear. Election Day in the two races is Jan. 5.
