18 states cut taxes in 2013. Utah was not one of them. The Washington Post notesa report from ALEC that says most of those states have Republican dominated legislatures with Republican governors.
The report, from the conservative American Legislative Exchange Council, catalogues the tax-cutting states, which stretch from Alaska to Florida. The bulk of those states — 13 of the 18 — have both Republican governors and Republican legislatures. A 14th, Nebraska, technically has a non-partisan unicameral legislature, though conservatives dominate the chamber.
Democratic governors of Montana and Arkansas signed tax-cut packages, while Democratic legislative chambers in Iowa and New Mexico passed their own tax cuts.
