How climate change and the Supreme Court are shaping 2020 for the 9th Congressional District

Once a reliably red state, Arizona has become increasingly purple over the last decade. 

When it comes to the 2020 election, it's districts like Arizona's 9th Congressional District that could swing outcomes on the federal level. 

The 9th Congressional District falls in the heart of the Valley. It includes east Phoenix, Tempe, south Scottsdale and parts of Mesa and Chandler. It's home to some of Arizona's largest employers, such as State Farm Insurance and Arizona State University. 

The district was originally drawn as one of three competitive House seats in Arizona. Back when it was created, Republicans had a 3 percentage point advantage. Today, Democrats have an 8-point edge. 

What does that shift mean for President Donald Trump and former Vice President Joe Biden? How could changing sentiments in one congressional district shape the outcome of November's election?

To find out, we talked to Representative Greg Stanton (D-Ariz.), who has served the district since 2018. We also talked to three different voters — one Democrat, one Republican and one Independent — to get their pulse on 2020. We asked them about which issues matter most to them, including climate change, health care and the Supreme Court vacancy. And we found out who they'll vote for in November.
