Obama brought a bunch of Somali, Sudanese, and Arab refugees into Boise and Twin Falls. Liberal areas are Sun Valley and Driggs/teton area. Home prices in Boise have tripled in recent years due to the number of Californians moving in. Boise was a great place to live 15 or more years ago.
Southern Idaho does have a lot of migrants and farm workers. Some places are still pretty awesome depending on what you're looking for. Taxes aren't really that low here. 6% sales tax on everything you buy even food and Amazon. Almost 8% income tax. Property tax isn't terrible depending on the town and county.
Salmon is a bit isolated but has good hunting, fishing, and recreation with enough stores to find what you need.
