Arizona Republicans are gambling they can win back their state with tax cuts. It might just work.

Republican leaders are crowing that this will increase Arizona’s economic growth rate, and they might be right. Large businesses won’t relocate on the basis of this bill, but individuals and families looking for lower costs of living might. Middle-income households in California face marginal state tax rates of between 4 and 8 percent, and families earning more than $115,648 pay a 9.3 percent marginal rate in the Golden State. These people would save thousands of dollars in taxes a year by moving across the Colorado River, and they would likely pay much less for a house, too. In the post-pandemic age of working from home, that difference could turn what is already a migration flood into a tidal wave.
