Sen. John McCain’s vote shutting down GOP hopes for repealing Obamacare will have wide-ranging ripple effects on Arizona politics into the 2018 elections.

On this weekend’s “Sunday Square Off,” the panel of Barrett Marson, political consultant at Marson Media; Chad Heywood, former Arizona Republican Party executive director and now a political consultant at Criterion Public Affairs; and Laurie Roberts, of the Arizona Republic, discuss why McCain cast his “no” vote and how it affects Gov. Doug Ducey, Sen. Jeff Flake and their current and potential 2018 opponents.
