Georgia's Senate is backing a plan to give the state's appointed election board the power to investigate Secretary of State Brad Raffensperger's handling of elections, despite the measure's sponsor saying that the bill is in “murky water” when it comes to its constitutionality. The Senate voted 30-19 along party lines Friday for Senate Bill 358, sending it to the House for more debate. The chamber's Republican majority also on Friday pushed through a proposal to ban ranked-choice voting in Georgia on a 31-19 party-line vote.
