NOEL KING, HOST:
Now let's hear NPR's Don Gonyea. He saw the debate at a Democratic watch party in a movie theater in Maricopa County, Ariz.
DON GONYEA, BYLINE: Arizona has long been reliably Republican in presidential contests - 16 over the last 17 times, in fact. But demographic changes are giving Democrats hope here.

CHUCK TODD: Twenty candidates qualified for this first debate. We'll hear from 10 tonight.
GONYEA: This audience watching on the movie theater screen in Scottsdale seemed to welcome this new phase of the campaign. After a section where the candidates' varying views on health care got an airing, retiree Sue Ellen Riley (ph) felt things were going well.
SUE ELLEN RILEY: I think health care, jobs and climate are our number one - 1a and 1b - issues in this country.
GONYEA: At one point, Senator Amy Klobuchar said President Trump conducts foreign policy in his bathrobe at 5 a.m. Congresswoman Tulsi Gabbard called Trump a chicken hawk. Such attacks did not impress schoolteacher and Democrat Jeff DeCoursey (ph).
JEFF DECOURSEY: They should spend time differentiating themselves from each other. You know, we all know who Trump is. He's been president for 2 1/2 years. You know, what is the point in going after him on these things when we already agree on that? Tell us what makes your policy different.
GONYEA: Some lamented the crowded debate stage. Still, 35-year-old government worker Rigo Gonzalez (ph) says it was good to get to hear specifics from candidates he didn't know well. I asked if watching eases his worrying about what may happen next year. No, he said.
So you're going to watch the second night.
RIGO GONZALEZ: Yes. Yes I am looking forward to it. I think, once again, it won't do much to ease the anxiety. But I'm looking forward to hearing what the second round of candidates have to say.
GONYEA: Different audience members praised different candidates afterwards. Several said they got active after the 2016 election and that Trump is keeping them involved this time.
