As Arizona schools and parents prepare this week for the state's first teachers strike in 40 years, what will organizers do if Gov. Doug Ducey doesn't agree to their demands?

On this weekend's "Sunday Square Off," our panel of Chad Campbell, a former House minority leader, and Paul Bentz, a political consultant and polling expert at Highground Consulting, agree that teachers union leaders would likely push for a statewide ballot initiative that would fund schools by raising taxes. See the video in the clip above.

Also on "Square Off":

-Why have Republicans spent $1 million to win an Arizona congressional seat they've held for four decades? Campbell and Bentz break down the polling in the Eighth Congressional District special election in the West Valley, and discuss whether Democratic newcomer Hiral Tipirneni has a chance to upset Republican Debbie Lesko in Tuesday's election.

-Arizona Republic reporter Daniel Gonzalez explains how a Donald Trump campaign rally inspired the paper's Pulitzer Prize-winning series "The Wall," and what he learned as one of the team of journalists working on it.
