I can’t figure out why Montana continues to re-elect Tester.
Montana is an interesting state, politically. It's reflexively a pretty conservative state, but it's also pretty conflicted. Demographically, it's a retirement state, having the 6th highest percentage of retirees of all the states. It's also among the states that are most dependent on Federal funds (39% of the State budget are federal dollars) and has a lot of agricultural business. Marijuana use is rampant in the western half of the state, too.
