Donald Trump’s support among Republican voters in Arizona dropped significantly following the GOP presidential debate but he still holds a double-digit lead over his opponents, according to a new poll.

An autodial poll conducted by the Las Vegas-based consulting firm Silver Bullet LLC showed the real estate mogul dropping to 24 percent of the vote, down from 33 percent several days earlier, prior to the debate. The second poll was conducted on Aug. 7, the day after 10 Republican contenders took the stage for the first debate of the presidential primary season.

Several candidates made big strides with Arizona voters following their performances in the debate. U.S. Sen. Marco Rubio, of Florida, made the biggest gain with a jump of 9 percentage points, followed closely by fellow U.S. Sen. Ted Cruz, of Texas, who gained 8 percentage points. Both are tied for second place in the poll with 13 percent.

Smaller gains were notched by neurosurgeon Ben Carson, who went from 10 percent to 12 percent, and former Arkansas Gov. Mike Huckabee, who went from 2 percent to 8 percent. Former Hewlett-Packard CEO Carly Fiorina jumped to 5 percent from 1 percent after what was widely viewed as a strong performance in an earlier debate for the seven GOP candidates who were outside the top 10 in recent polls.

Trump wasn’t the only candidate who lost support after the debate, which was hosted in Cleveland by Fox News. Wisconsin Gov. Scott Walker lost 9 percentage points, the same amount as Trump, dropping to just 4 percent, and former Florida Gov. Jeb Bush fell to 12 percent from 17 percent.

As in its Aug. 3 poll, Silver Bullet asked undecided respondents who they would vote for if they had to make a choice. Only 7 percent continued to say they were undecided after the follow-up question.

The automated poll of 553 self-identified likely GOP primary voters was conducted on Aug. 7 via landline. The firm polled only Republicans who had voted in one of the last three Republican primaries in Arizona, including the 2012 presidential primary. The poll had a margin of error of +/- 4.17 percent, according to Silver Bullet.

Despite a debate performance in which he got into a testy exchange with moderator Megyn Kelly and refused to rule out a third-party run for president if he didn’t win the Republican nomination, Trump remains atop the polls, both in Arizona and nationally. An online poll commissioned by NBC News after the debate showed him holding steady with 22 percent of the vote, just 1 percentage point down from a pre-debate poll.
