House Republicans are scheduled to caucus Tuesday night at the State Capitol to pick a replacement for Tim Armstead, who resigned last week to run for a seat on the State Supreme Court, and has since been appointed to the Court. Armstead is the only Speaker the Republicans have had since assuming the majority in the 2014 election, and he was typically chosen by acclimation in caucus and then a roll call vote on the floor, but now there is a campaign on for the powerful leadership position.
