Harris campaign touts Republican Mesa mayor's support in new Arizona ad

Vice President Harris’s campaign launched a $370 million ad blitz on Monday, debuting a 30-second spot highlighting an Arizona Republican mayor’s support for the Democratic nominee.

In the new ad, called “Cities,” Mesa Mayor John Giles said he is voting for Harris because Harris puts “country over party” and would be “an adult” in the White House.

“In cities like mine, folks look out for each other. They put their community first,” Giles began in the ad.

“I'm a lifelong Republican, but I’ve always put country over party, and I know Donald Trump’s second term would be all about himself,” he continued. “That’s why like so many other Republicans, I cannot support Donald Trump.”

“Kamala Harris and I may not agree on everything, but I do know that she will always put country first. If we’re gonna make progress as a country, we have to have an adult in the White House. That’s why I’m supporting Kamala Harris,” he said.

The ad is part of a broader ad campaign aimed at reaching GOP and independent voters. The effort launched on Labor Day and will last for three weeks, until Election Day. The “Cities” ad will air on Fox News, as well as on local broadcast and cable shows, like "Fire Country," "Shark Tank," and "Chopped," according to the Harris administration.

The Harris campaign has focused on highlighting her support from Republican officials. Harris recently received endorsements from former Sen. Jeff Flake (R-Ariz.) and former Rep. Liz Cheney (R-Wyo.).

Harris’s campaign said she has the support of more than 120 current and former Republicans in Arizona.

Arizona is one of the seven closely watched battleground states that appears within reach for either candidate to win.

Trump is currently leading Harris 48.8 percent to 47.4 percent in the state, according to the latest polling average from Decision Desk HQ/The Hill.
