PHOENIX -- Arizona legislators on Wednesday begin holding closed-door party caucuses to pick leaders for the next two years.
The process starts with Republicans who saw their majorities shrink in Tuesday's general election.
Senate President Steve Pierce faces a challenge from current Majority Leader Andy Biggs, a conservative who a year ago suggested that the state drop out of the federal Medicaid program.
In the House, Speaker Andy Tobin faces a possible challenge for the top leadership post from Steve Smith, a senator who won a House seat Tuesday.
House and Senate Democrats are scheduled to hold their separate caucuses on Thursday.
