Appointed U.S. Senator Luther Strange and former Alabama Supreme Court Chief Justice Roy Moore will be going head-to-head on September 26 because neither candidate received more than 50 percent of the vote in the first round of the Republican primary election.

President Trump and establishment Republicans have lined up behind Strange, but Moore has wide appeal among religious conservatives across the Yellowhammer State.

The winner of the runoff election will face Democrat Doug Jones, a former U.S. Attorney who coasted to victory in the first round, on December 12.
