The battleground state, where Kamala Harris will rally on Friday, has drifted toward Donald Trump since he lost it in 2020. Democrats hope her momentum could turn their fortunes around there.
As Vice President Kamala Harris fights for the votes of Americans threatening to abandon the Democratic Party, she faces challenges across the battleground states, from working-class Nevada communities to Arab American enclaves in Michigan.
But perhaps no swing state has vexed Democrats as much this year as Arizona.
A longtime Republican stronghold before President Biden’s victory in 2020, the state is tricky political territory for Democrats, who confront magnified concerns over the number of migrants coming across the U.S.-Mexico border. A handful of polls in recent weeks have shown former President Donald J. Trump leading Ms. Harris by the mid-single digits, even as her numbers have improved in other vital states.
On Friday, Ms. Harris will take the stage in a Phoenix suburb alongside her new running mate, Gov. Tim Walz of Minnesota — part of a renewed push to put Sun Belt states back in play and keep Arizona’s 11 electoral votes in the Democratic column. She faces an uphill battle there as Republicans work to paint her as the architect of the border crisis, but her allies say the energy she has brought to drained Democratic voters could also attract moderate swing voters.
“She seems to have captured some of that lightning in a bottle that the Obama campaign had,” said John Giles, the Republican mayor of Mesa, east of Phoenix, who endorsed Ms. Harris last month. Still, he cautioned, “she absolutely has to run like she’s behind in Arizona, because I think she is.”
