This is how the West is run: In the 13 westernmost U.S. states, one party controls both the executive and legislative branches.

Flush with federal cash, the region — the fastest-growing in the country — is rebuilding from the disruptions of the still ongoing COVID-19 pandemic, and states’ political leanings will play a role in how they budget for their future.

Republicans run state governments in Alaska, Arizona, Idaho, Montana, Utah and Wyoming. Democrats run California, Colorado, Hawaii, Nevada, New Mexico, Oregon and Washington. On a color-coded map, it’s a solid blue contiguous Pacific coast bordered by red Republican country in the Intermountain West and a trio of Democratic flyover states.

State budgets today are bulked up with federal stimulus from a pair of bills signed by President Joe Biden last year: the American Rescue Plan Act, which allocated $195.3 billion for states to be spent by 2026, and the Infrastructure and Investment and Jobs Act, which will funnel billions to states for projects like bridges, roads, public transportation, broadband and electric vehicle charging stations.

“I think you’re going to see the difference at the margins,” said David Damore, professor and chair of the department of political science at the University of Nevada, Las Vegas, of how states spend their budget surplus. “What type of infrastructure? Do we try to do mass transit versus roads? I think you’ll see differences in red states, but it’ll be in the margins.”
