Former Alabama Supreme Court Justice Roy Moore is consolidating anti-establishment conservative support in Alabama’s Senate race more than a week before voters head to the polls.

Moore, a Christian conservative known as the “Ten Commandments Judge,” has been polling ahead of incumbent GOP Sen. Luther Strange ahead of Sept. 26’s Republican primary runoff.

In a major boost for his campaign on Saturday, Moore was endorsed by Alabama GOP Rep. Mo Brooks, a House Freedom Caucus member who came in third place during the initial Aug. 15 primary.

During a rally in Huntsville, Brooks said he already voted absentee ballot for Moore and called out Senate Majority Leader Mitch McConnell, who backs Strange and whose political operation attacked Brooks during the primary.

“The Strange/McConnell forces maliciously and personally attacked and maligned me,” Brooks said Saturday. “They are doing the same to Roy Moore.”

Strange, the former attorney general in Alabama, was temporarily appointed to the seat in April after then-Sen. Jeff Sessions joined the Trump administration. Favored by establishment and business Republicans, Strange has also been endorsed by both President Trump and Vice President Mike Pence.

But despite Strange’s support from Trump, Moore has steadily been rolling out endorsements in recent weeks from well-known anti-establishment conservatives, including former Alaska Gov. Sarah Palin, former Arkansas Gov. Mike Huckabee and former Oklahoma Sen. Tom Coburn.

“In the special election runoff for the Republican nomination for the U.S. Senate pitting constitutional conservative Roy Moore against former D.C. lobbyist/current swamp denizen Luther Strange, there is no contest – Roy Moore wins, hands down,” Jenny Beth Martin, chairperson of the Tea Party Patriots Citizens Fund, said in a statement this week.

Moore has also been endorsed by several conservative federal lawmakers, including Kentucky Sen. Thomas Massie, Ohio Rep. Jim Jordan and North Carolina Rep. Mark Meadows.

"I am proud to endorse Judge Roy Moore for the U.S. Senate… I look forward to working with him to advance conservative principles by repealing ObamaCare, passing real tax reform and securing our borders,” said Meadows, chairman of the House Freedom Caucus.

MOORE'S STAR RISING IN ALABAMA SENATE RUNOFF RACE

Polling since the initial primary have shown Moore leading Strange. But the Senate Leadership Fund, a super PAC with ties to McConnell, circulated a poll last week that shows Strange down a point.

But as he’s risen in the polls, Moore has come under more scrutiny and has been the subject of negative news stories.

Old video surfaced of Moore questioning whether former President Barack Obama was a natural-born citizen.

It was also reported this week that Moore, during a speech at a Baptist church earlier this year, suggested that the Sept. 11 attacks were punishment because America had distanced itself from God.

And opponents have seized on news reports scrutinizing the Foundation for Moral Law, an organization connected to Moore, that has not filed its taxes since 2014.

“Every day that goes by, the Moore family foundation looks more like the Clinton family foundation,” said Steven Law, CEO of the Senate Leadership Fund.

The winner of the GOP runoff will face Doug Jones, a former U.S. attorney under the Clinton administration who was endorsed by former Vice President Joe Biden.

Alabama hasn’t elected a Democrat to the Senate in more than 20 years.
