Arizona Mirror editor says changing demographics could shift battleground state in Biden's favor

The latest ABC News-Washington Post poll found Trump leading Biden among voters in Arizona by a slim margin — 49 percent to 48 percent. The poll also reported a tight race for Senate in Arizona, with Democrat Mark KellyMark KellyDemocratic incumbents bolster fundraising advantage in key Senate races Warnock raises .5 million in third quarter Anti-Trump Republicans endorsing vulnerable Democrats to prevent GOP takeover MORE at 49 percent and Sen. Martha McSally (R) at 48 percent among likely voters.

Duda said during an interview on Hill.TV Friday that these tightening margins could be explained by an increase of Democratic support in Maricopa County, home to more than 4 million people and accounting for more than 60 percent of the state's population. The area, which also includes the city of Phoenix, has become increasingly blue over the years. 

Races for the legislature are getting closer, the margins are narrower than they’ve been since the 1960s for the Democrats,” Duda said. 

“You’re definitely seeing some changes, and it’s hard to say whether that’s a result of Trump or if it’s really a result of real long-term changes that will probably take a few more election cycles to really get a handle on that,” Duda added. “But at least for now, things are much more in play for Democrats than they normally would be.”
