Former Chief Justice Roy Moore holds a notable lead in the Alabama Republican Senate primary, according to a poll released Monday.

The survey of 500 Republican voters by Louisiana-based JMC Analytics and Polling – which reached a large number of groups traditionally supportive of Moore – found judge leading the crowded GOP field with 30 percent of the vote. U.S. Sen. Luther Strange got 22 percent of the vote, while U.S. Rep. Mo Brooks, R-Huntsville, had 19 percent. The poll has a margin of error of plus or minus 4.4 percent.

“Roy Moore leads the field based on his strength in northern Alabama, while Luther Strange runs relatively strongly across most of the state,” JMC stated in a summary section. “Mo Brooks has regional strength in the Huntsville media market while garnering at least 10 percent in the other media markets.”

Sen. Trip Pittman, R-Montrose, got 6 percent of the vote, while Dr. Randy Brinson, the former head of the Christian Coalition of Alabama, got 2 percent. Seventeen percent of those surveyed said they were undecided.

The poll leaned toward groups Moore does best in. 70 percent of those surveyed described themselves as evangelical Christians. 47 percent were aged 65 and older.

Perhaps as a result, Moore came out well in the poll. 53 percent of those surveyed said they had a favorable view of Moore, while 34 percent said they had an unfavorable view. Strange and Brooks were both underwater with those polled. 31 percent had a favorable view of Brooks, while 43 percent had an unfavorable view. 35 percent had a favorable view of Strange, while 50 percent had an unfavorable view.

The majority of those surveyed – 56 percent – said economic issues were most important to them. 17 percent cited social issues, and 16 percent cited immigration.

The primary will take place Aug. 15. The Alabama Secretary of State’s office estimates turnout for the primary will be in the 20 to 25 percent range. A runoff will take place Sept. 26 if no candidate receives a majority of the vote.

A poll released last week by RRH Elections had Moore and Strange in a virtual tie, with Brooks a distant third.

JMC conducted the automated, landline-based poll between Aug. 5 and 6. The poll chose households based on their recent participation in primaries.
