After the Great Recession Arizona did a “temporary” increase in (sales, I believe) tax to make up for the deficit and it really was temporary.

Coming from California temporary tax means “until the heat death of the universe” so I was very surprised.

Given that Wyoming makes up around 0.2% of the US population, I guess the original claim that "almost[!] no one in power in the USA is actually low taxes and low spending" might be pretty reasonable.
