Voters in four Alabama counties are going to the polls to fill three vacancies in the Alabama House of Representatives. House District 31 in Elmore and Coosa counties is having a Republican runoff between Mike Holmes and Jimmy Collier. The winner has no Democratic opposition. Voters in part of Jefferson County are choosing between Anthony "Alan" Johnson and Arthur Shores Lee in the Democratic runoff for House District 53. The winner faces Republican Willie "W.A." Casey in March. Voters in part of Mobile County are deciding whether Republican Margie Wilcox or Democrat Stephen Carr will represent District 104. The polls are open from 7 a.m. until 7 p.m. Tuesday. The special elections were originally scheduled Jan. 28, but Gov. Robert Bentley delayed them one week due to the ice storm.
