Liberal group urges Alabama voters to write in football coaches Nick Saban, Gus Malzahn Voters head to the polls tomorrow in Alabama's closely watched U.S. Senate race.

 -- In an attempt to capitalize on college-football-crazed Alabamians, a liberal super PAC is urging voters in the state to write in the names of the head coaches of the University of Alabama and Auburn University football teams in Tuesday's closely watched U.S. Senate special election.

The group, American Bridge 21st Century, is releasing two 15-second Facebook advertisements targeting Republican voters, telling them to write in Nick Saban, Alabama's head coach, or Gus Malzahn, Auburn's head coach.

Representatives from the University of Alabama and Auburn did not respond to ABC News' request for comment.

While Donald Trump won Alabama by nearly 30 percentage points in the 2016 presidential election, Democrats are hoping their candidate, Doug Jones, a former U.S. attorney, can pull off an upset in the wake of allegations of sexual misconduct against Republican nominee Roy Moore, a former judge.

Moore faces multiple allegations of sexual misconduct with women when they were in their teens and he was in his 30s. He has denied the allegations.

Some recent polls have shown a close race.

"Roy Moore's disgraceful actions make him unfit for public service. Alabama voters have a chance to stand up for moral values on Tuesday, and as Coach Saban says, 'Character is what you do when no one else is watching,'" American Bridge President Bradley Beychock said in a statement released Monday.

While both coaches are well-known figures in the state, neither has indicated any interest in running for public office.

Alabama is scheduled to take on Clemson University in the first round of the College Football Playoff on New Year's Day, and Auburn is taking on the University of Central Florida in the Chick-fil-A Peach Bowl the same day.

Your Voice, Your Vote: ABC News will have live coverage of the Alabama special election on Tuesday night at 8:30 p.m. ET on ABCNews.com, Facebook, Twitter, YouTube and the ABC News app.
