RRH Elections AL-Sen R Primary Poll: Moore Leads Strange 31-29

Moore, Strange likely headed to runoff; Brooks likely to finish third; Race for first is tight and runoff may be very competitive

With less than two weeks until the closely-watched special Republican primary for the Alabama US Senate seat, a new RRH Elections poll shows the race for first place in the primary tight between former State Supreme Court Justice Roy Moore (R) and appointed Sen. Luther Strange (R). Moore leads Strange 31% to 29%, with both candidates likely to appear in a runoff. Rep. Mo Brooks (R) trails in third with 18%. Two other candidates, State Sen. Trip Pittman (R) and physician and evangelical leader Randy Brinson (R), poll in single digits. The survey of 426 likely Republican voters was conducted between July 31 and August 3, 2017 using both an IVR automated phone survey (369 voters) and an online survey (57 voters). It has a margin of error of 5%. All survey design and data analysis is the responsibility of RRH Elections; funding was provided by the generous contributions of our readers.

Moore 31%
Strange 29%
Brooks 18%
Pittman 8%
Brinson 2%
Undecided 11%
Total 100%


Moore/Strange Runoff  
Moore 34%
Strange 32%
Undecided 35%
Moore/Strange Runoff by 1st Round Choice Moore Strange Brooks   Pittman   Brinson   Undecided
Moore 73% 3% 32% 23% 30% 17%
Strange 3% 70% 16% 39% 24% 30%
Undecided 24% 26% 52% 38% 46% 53%

The likely Moore-Strange runoff starts as highly competitive, with both candidates taking about a third of the vote and many undecideds. Neither runoff candidate pulls a commanding share of the votes from the three eliminated contenders.

Moore/Brooks Runoff
Moore 43%
Brooks 20%
Undecided 37%
Strange/Brooks Runoff
Strange 42%
Brooks 22%
Undecided 36%

Brooks will start as a decided underdog in the runoff – to either Moore or Strange – if he overcomes his third-place position in our poll.

Trump Opinion  
Strongly Approve 62%
Somewhat Approve 23%
Somewhat Disapprove 9%
Strongly Disapprove 5%

As one would expect for Republican primary voters in deep-red Alabama, our sample strongly approves of President Trump’s job performance.


18 to 44 14%
45 to 64 36%
65+ 49%
Female 49%
Male 50%
Polling Method  
Online (Google Surveys) 17%
Phone (PMI Inc.) 83%

Like many primary electorates, this race’s electorate skews older. The electorate is also roughly evenly divided between males and females.


Congressional District  
1 12%
2 19%
3 10%
4 16%
5 15%
6 18%
7 9%

The sample electorate is dispersed throughout the state, though the higher-income Montgomery and Birmingham areas will likely have somewhat higher turnout than the more rural parts of the state. As expected, turnout is lowest in the 7th district, the state’s only heavily Democratic district.


Age 18 to 44 45 to 64 65+
Moore 24% 36% 30%
Strange 32% 24% 33%
Brooks 26% 22% 13%
Pittman 11% 6% 9%
Brinson 3% 2% 3%
Undecided 5% 11% 13%

Interestingly, our poll does not reveal a particularly significant age gap. However, Moore does seem to perform well with middle-aged voters, while Brooks seems to do best among younger voters.

Gender Female Male
Moore 34% 30%
Strange 30% 28%
Brooks 15% 20%
Pittman 7% 8%
Brinson 1% 4%
Undecided 13% 10%

Also interestingly, there is essentially no gender gap in this race.

Trump Approval Strongly Approve Somewhat Approve Somewhat Disapprove Strongly Disapprove No Opinion
Moore 36% 33% 25% 9% 25%
Strange 33% 26% 16% 4% 32%
Brooks 10% 16% 33% 36% 32%
Pittman 7% 8% 5% 16% 9%
Brinson 3% 0% 0% 4% 2%
Undecided 10% 17% 21% 31% 0%

Despite Strange’s attempts in advertising to tie himself to Trump, he actually slightly trails Moore among voters that strongly approve of Trump’s performance. Meanwhile, ads hitting Brooks as insufficiently loyal to Trump seem to be producing the desired effect, as his numbers have been hurt among the president’s most fervent supporters and boosted among the small minority that disapprove of Trump.

Congressional District 1 2 3 4 5 6 7
Moore 31% 43% 35% 29% 18% 25% 40%
Strange 27% 21% 24% 40% 20% 38% 33%
Brooks 7% 15% 22% 15% 39% 15% 13%
Pittman 20% 8% 7% 7% 6% 4% 4%
Brinson 1% 3% 2% 0% 5% 3% 2%
Undecided 13% 9% 10% 8% 12% 16% 8%

Geographically, Moore is strongest in the southern half of the state, Strange does best in the Birmingham area, and Brooks wins his northern 5th district. Pittman has a base in the Mobile area but little appeal outside of the 1st district.

Discussion & Analysis:

With eleven days until Election Day, the Republican Primary race for the US Senate seat in Alabama looks certain to head to a runoff. Ex-State Supreme Court Justice Roy Moore is leading appointed Senator Luther Strange 31%-29%, making them essentially tied. Both are well short of the 50% mark needed to win outright. Indeed, with only 11% undecided, the chance of a win for either on August 15th seems remote.

The third candidate considered a contender, Rep. Mo Brooks, is running well behind the two front-runners with 18%. Brooks has been battered by ads over his prior skepticism of President Trump, who now finds himself incredibly popular among the primary electorate. Brooks’s best chance at upsetting the likely Moore/Strange pairing may be through a fourth candidate, State Sen. Trip Pittman, who has little chance to make a runoff. Like Brooks, Pittman is an anti-establishment conservative, and his strongest area, Mobile, is also Brooks’s weakest. If Pittman were to make an exit from the race and endorse Brooks, their aggregate vote share could put Brooks back into contention.

Looking ahead to the September runoff, which is likely to be between Moore and Strange, our poll shows it will start as a tossup with many undecideds. Both Moore and Strange have vulnerabilities. Strange has been under fire for his questionable ties to disgraced ex-Gov. Robert Bentley, and Moore is well-known for holding polarizing social conservative views. As a result, neither automatically gains the votes of the three other candidates in a second round, and the runoff is likely to be hard-fought. But for now, both Moore and Strange should at least feel good about their chances of surviving the first round.


The survey was conducted according to the script that follows in the appendix; to make the survey length manageable and increase response rates, only the 5 highest-profile candidates as determined by RRH Elections were tested. Data was collected through two methodologies and thereafter synthesized and weighted by RRH Elections: 369 Interactive Voice Response (IVR) calls were placed to a list of randomly selected Alabama voters who had participated in two of the last three Republican Primary elections, by PMI, Inc. of Marianna, Fla., while 57 online surveys were collected using the Google Surveys platform. IVR surveys make up 83% and online polls comprise 17% of survey data due to weighting. All respondents were asked their likelihood to vote, and those that were unlikely to vote or who did not complete the topline question (Question 2) were not included in the survey. Demographic data was collected in different ways between the samples: IVR demographics were asked of the respondents, while online demographics were inferred by Google’s algorithm. Geography was determined by the voter file for IVR responses and by Google’s algorithm for online responses. Survey data was weighted by RRH Elections for age only. Random deletion was not used as a method of weighting.
