Walz calls Trump a 'dictator' who wants to 'overturn the Constitution'

"Someday you're going to be sitting on that porch. You're going to be in that rocking chair, and a little one is going to come up to you after being in school where they've been studying the 2024 election, and they're going to ask when everything was on the line and the American experiment was on the line, and there was somebody running who asked to be a dictator and to overturn the Constitution and talk about using the military against our own people. What did you do to stop that from happening?" Walz told the crowd on Saturday. 

"And you're going to be able to say every damn thing we could, every damn thing we could," he said. 

Walz closed his speech by saying: "Make a plan to vote. Make a plan to get out and canvass. Make a plan to take a neighbor to the polls." 

In eight high-quality polls conducted in Arizona since August, Trump has been ahead in seven. His edge has been between 1-6 points. 

Immigration continues to be a highly important issue in Arizona, which shares a border with Mexico.  

In the latest Wall Street Journal survey, 25% of voters said immigration was the most important issue to their vote, higher than any other battleground. It was a "deal-breaker" issue for 24% of voters. And Arizona voters preferred Trump on the issue by 10 points.
