Republican Kari Lake is closing in on Democrat Ruben Gallego in Arizona’s U.S. Senate race, according to the results of a poll released just days before Election Day.

The poll released on Friday by YouGov/The Times of London/SAY24 finds Lake trailing Gallego by 5 percentage points. A 49 percent plurality of registered Arizona voters said that they were backing Gallego, while 44 percent chose Lake. The poll was conducted from October 25 to October 31 and has a 4.4 percent margin of error.

Lake was performing considerably worse in a poll released by YouGov/CBS News on October 18, with the Republican candidate trailing the Democrat by 9 points among likely voters—54 percent of respondents said they would vote for Gallego and 45 percent preferred Lake. The poll was conducted from October 11 to October 16 and has a 3.3 percent margin of error.

Gallego, who represents Arizona’s 3rd Congressional District in the U.S. House of Representatives, still has a lead over Lake in the vast majority of polls. However, the congressman has seen his advantage shrink in the closing weeks of the contest, with some recent surveys suggesting that the race is effectively tied.

An AtlasIntel poll conducted on October 30 and October 31 and released on Friday showed Lake with a tiny 1 point advantage among likely voters. However, the survey was one of only three public polls showing the Republican with an advantage during the entire election cycle, all by just 1 point.

In comparison, Gallego has had 15 different polls showing him with a double-digit lead over Lake. A RABA Research survey released on Monday and conducted from October 25 to October 27 showed the Democratic congressman with a massive 15 point edge among registered Arizona voters.

Newsweek reached out for comment to the Lake and Gallego campaigns via email on Friday night.

A spokesperson for the Lake campaign previously told Newsweek that “the momentum is with” Lake and former President Donald Trump heading into the November 5 election, with the campaign expressing confidence “that Arizonans will deliver both Trump and Lake a victory.”

Lake has polled significantly behind Trump in polls despite frequently touting her devotion to the ex-president. Trump was leading Vice President Kamala Harris in Arizona by just 1 point, 48 percent to 47 percent, in Friday’s YouGov/The Times of London/SAY24 poll.

After narrowly losing Arizona’s gubernatorial election to Democratic Governor Katie Hobbs in 2022, Lake echoed Trump’s post-2020 election denialism by claiming without evidence that the contest had been “stolen” while launching a series of failed lawsuits to overturn the outcome.

Lake continued to refuse to admit that she lost to Hobbs during an interview with CNN’s Kaitlan Collins on Monday, lashing out at Collins for “looking backward” after being asked at least seven times whether she would accept the reality of her defeat.
