Municipality Overview


In 2020, the East Valley’s shift from a solid base of GOP support to an increasingly purple section of the Phoenix-Metro steadily continued.

Driver of Shift, Education


In 2010, 50% of college educated voters identified themselves as Republicans.

In 2020, 37% of college educated voters identified themselves as Republicans.

This significant change in college educated voter preference is the most obvious cause of the increasing Democratic performance in high educated areas like Chandler and Gilbert.

Driver of Shift, Diversity


While Chandler and Gilbert create structural disadvantages for Republicans due to their high level of college educated voters, Mesa creates problems of its own.

Mesa is one of the most diverse areas in the Phoenix-Metro, most notably in Central Mesa.

This is an area that Republicans performed surprisingly well in 2016, but is now an area of weakness due to increased turnout among Hispanics who largely favor Democratic candidates.

Republicans did make gains nationwide with Hispanic voters in 2020, and I anticipate those gains being durable going in to 2022 and causing a deceleration in Mesa’s shift to Democrats.

Driver of Shift, Growing Metro Influence


Proximity to Phoenix’s city center is the most significant driver of weakening GOP performance.

Without a change in political environment, 2022 will see Phoenix’s sphere of influence expanding into Gilbert, and solidifying gains in Central Mesa.

What should concern the GOP the most is the stickiness and widespread nature of the Democratic gains in areas around Phoenix. We have yet to see these gains be reversed, they so far have stuck and deepened. 2022 could be that year, but it would require changes in public opinion on the national level.
