Former Alabama Supreme Court Chief Justice Roy Moore leads the crowded Republican primary field in the state's Senate race, according to a new poll.

Moore has 30 percent support in the JMC Analytics and Polling survey. He is followed by Sen. Luther Strange (R-Ala.), with 22 percent, and Rep.

The poll found that 53 percent of respondents view Moore favorably, compared with 34 percent who have an unfavorable opinion of him.

Just 35 percent have a favorable view of Strange and half of respondents see him unfavorably.

About one-third, 31 percent, have a favorable impression of Brooks, compared with 43 percent who have an unfavorable opinion of him.

The poll of 500 Alabama residents was conducted from Aug. 5-6. Its margin of error is 4.4 percent.

Last month, Brooks sparked controversy with a campaign ad using audio from the June shooting that injured House Majority Whip Steve Scalise (R-La.).
