HUNTSVILLE, Alabama — It has been a week since Alabama Republicans went to the polls to select who they preferred to face incumbent Sen. Doug Jones (D-AL) in November.

Coming out of that contest were two candidates, former Auburn University head football coach Tommy Tuberville and former U.S. Attorney General Jeff Sessions, who will go head to head in a runoff given neither could achieve the majority necessary to secure the GOP nomination.

On Tuesday, President Donald Trump gave his endorsement on Twitter to Tuberville, over his former attorney general:

Tommy Tuberville (@TTuberville) is running for the U.S. Senate from the Great State of Alabama. Tommy was a terrific head football coach at Auburn University. He is a REAL LEADER who will never let MAGA/KAG, or our Country, down! Tommy will protect your Second Amendment…. — Donald J. Trump (@realDonaldTrump) March 11, 2020

….(which is under siege), is strong on Crime and the Border, and truly LOVES our Military and our Vets. He will be a great Senator for the people of Alabama. Coach Tommy Tuberville, a winner, has my Complete and Total Endorsement. I love Alabama! — Donald J. Trump (@realDonaldTrump) March 11, 2020

The Trump endorsement comes on the heels of a strong showing from Tuberville in a poll conducted by Cygnal Polling and Analytics that showed if the March 31 runoff election were held today, Tuberville would receive 51.5% of the vote, with 39.5% going for Sessions.

Both campaigns released internal polling later in the day, with a Sessions internal poll, conducted by On Message, Inc. from March 8-9, showing the race deadlocked at 45% each, and the Tuberville internal poll, conducted by Moore Information Group on March 5 and 7, showing Tuberville with 49% and Sessions at 38%.

Tuberville responded via social media shortly after Trump’s tweet:

Alabama Republicans will have an opportunity to cast a ballot on March 31 in the primary runoff.
