Geoff Duncan: The president of the Senate, Duncan, a former House member, will get on-the-job training early on in a chamber whose majority caucus didn't back his campaign. However, he's got a veteran political consultant running his office and a ready-made signature issue — a tax break he promoted to persuade companies and individuals to donate big money to help keep rural hospitals afloat.
Butch Miller, R-Gainesville,
Senate president pro tem: A floor leader for Gov. Nathan Deal, Miller is a car dealer used to wheeling and dealing at the statehouse as well. Miller was considered a possible candidate for lieutenant governor before last year's race and is seen as a likely future candidate for office such as the U.S. Senate.
Mike Dugan, R-Carrollton, Senate majority leader: A U.S. Army Ranger who retired as a lieutenant colonel in 2008, Dugan, like Miller, is personable and has the ability to clearly explain the Senate Republican stance on issues. Like Miller, he was also a floor leader for Deal. He won over the Republican caucus that had been led by Sen. Bill Cowsert, R-Athens, the new governor's brother-in-law.
Jack Hill, R-Reidsville: A retired grocer who has long run the Senate Appropriations Committee, he's a former Democrat whose party switch helped the Senate turn Republican in 2002. Hill follows economic indicators closely and knows everything about how state tax money is spent, and he plays a key role in deciding where it goes.
Chuck Hufstetler, R-Rome; An anesthetist, Hufstetler rose quickly after being elected in 2012 and runs the Senate Finance Committee, which considers tax legislation and is one of the most active late-session panels at the Capitol. He's been involved in a wide range of issues including health care and ethics, and he hasn't been afraid to stand against his Republican colleagues on issues.
Others: Rules Chairman Jeff Mullis, R-Chickamauga; Minority Leader Steve Henson, D-Tucker; Sen. Rene Unterman, R-Buford; Sen. Nikema Williams, D-Atlanta.
David Ralston, R-Blue Ridge, speaker: The level-headed, plain-spoken mountain lawyer has earned high marks for leading a chamber that can be raucous and fractious at times. He faces increasing pressure from the right within his own caucus, but he has managed to maintain control when it matters.
Jan Jones, R-Milton, speaker pro tem: She's seen as a smart, stable leader from a politically important part of metro Atlanta. A former journalist and marketing executive, Jones is the highest-ranking woman in General Assembly history. Last year, she headed a committee to review how the House and Senate handle sexual harassment issues.
Terry England, R-Auburn, House budget chairman: England was Ralston's choice to take over the money committee, and like his Senate counterpart Hill, he is an extremely hardworking lawmaker who follows the state's finances closely and knows where pretty much every cent of the state's $26 billion budget is spent.
Bob Trammell, D-Luthersville, minority leader: An attorney, Trammell was picked to replace Stacey Abrams, the party's nominee for governor last year. He has been more publicly aggressive on some issues than Abrams in that role, but he strongly backed her candidacy for governor. Trammell narrowly won re-election against an opponent who might — or might not have — lived in the district and followed it up by winning a caucus vote to continue leading the Democrats in the House.
Jay Powell, R-Camilla, new chairman of the House Rules Committee: Powell, a lawyer, is best known for handling big tax legislation as chairman of the Ways and Means Committee. Like Mullis in the Senate, Powell plays a major role in deciding which legislation gets to the floor of the chamber for a vote and which bills die.
Others: Majority Leader Jon Burns, R-Newington; Rep. Brett Harrell, R-Snellville; Health and Human Services Chairwoman Sharon Cooper, R-Marietta.
