A survey of voters likely to participate in the Republican primary for the U.S. Senate next year showed most respondents had an unfavorable opinion of former Alabama Supreme Court Chief Justice Roy Moore.

The polling firm Cygnal released the results today of the survey of 612 likely GOP primary voters conducted June 22-23.

Moore announced his candidacy for the Senate seat held by Sen. Doug Jones on June 20.

Respondents to the Cygnal survey were asked their opinions of several other GOP candidates for the Senate seat -- U.S. Rep. Bradley Byrne of Fairhope, former Auburn football coach Tommy Tuberville, Secretary of State John Merrill, and state Rep. Arnold Mooney of Shelby County.

Moore, 27.7 percent favorable, 65.4 percent unfavorable.

Byrne, 41 percent favorable, 11.1 percent unfavorable.

Tuberville, 55.6 percent favorable, 16.5 percent unfavorable.

Merrill, 31.6 percent favorable, 10.1 percent unfavorable.

Mooney, 6.4 percent favorable, 6.8 percent unfavorable.

Merrill announced his candidacy on Tuesday.

Brent Buchanan, Cygnal’s CEO and founder, said President Trump’s negative stance toward Moore’s candidacy has damaged Moore. The president tweeted last month that he did not think Moore could win. Jones defeated Moore in a special election in December 2017 after Moore’s campaign was damaged by news reports of sexual misconduct with teenage girls decades ago, allegations that Moore said were false.

Moore, asked for comment on the poll today, said via a direct message on Twitter: “According to another recent poll I would beat Doug Jones by 61% to 31% but polls don’t win national championships in football nor do they win elections for U.S. Senate. I know that Alabama voters will be smart as they have been in the past and will disregard polls used by the Establishment to warp our election process.”

Respondents to the Cygnal survey were also asked if the primary was held that day who would they vote for from the following list:

Tuberville, 29.3 percent.

Byrne, 21.4 percent

Moore, 13 percent

Merrill, 11.8 percent.

Mooney, 2.2 percent.

Undecided, 22.3 percent.

Trump and Gov. Kay Ivey both had strong favorable ratings.

Trump, 84.3 percent favorable, 14.9 percent unfavorable.

Ivey, 75 percent favorable, 19.8 percent unfavorable.

The margin of error in the poll was plus or minus 3.96 percent.

More results from the Cygnal survey. The firm said in its press release on the survey that it’s not working with any candidate in the Senate race.
