Alabama voters headed to the polls Tuesday to decide a handful of key primary runoffs. The biggest race is between Rep. Martha Roby, a Republican who was forced into a second round of balloting when just 39 percent of the vote on June 5, and former Rep. Bobby Bright. Roby has struggled over the perception she is not sufficiently loyal to President Trump, but Bright last served in Congress as a Democrat who voted for Nancy Pelosi for speaker. Trump has endorsed Roby.
