The balance of the power in the US Senate will be decided Tuesday night with two runoff elections in Georgia. Republican incumbents Kelly Loeffler and David Purdue are in a neck and neck battle with Democrat challengers Raphel Warnock and John Ossoff. Should Democrats be able to pull off the two victories, they would take power in the US Senate with vice president-elect Kamala Harris serving as the tie breaking vote. Should Republicans win won or both seats they will maintain their slim majority in the Senate. South Dakota Governor Kristi Noem was in Georgia Sunday serving as a campaign surrogate for Purdue and Loeffler.
