Keith Allred, the Democratic candidate for governor, said the state's new highway cost allocation study, released today, validates his longstanding criticism that current Gov. Butch Otter has been favoring "special interests" over Idaho citizens, particularly when the governor proposed a big car registration fee increase but only a small hike for trucks; Otter wanted a study before further changing truck fees. That proposal, like Otter's proposed gas tax increase, failed to pass the Legislature. Allred said he also opposes a gas tax hike. “Raising the gas tax is wrong for three reasons," he said in a statement. "First, this is no time to be raising taxes on Idaho families. Second, we have other far more pressing priorities than roads right now, our kids’ education chief among them. Third, raising the gas tax does nothing to correct the unfairness of car and pickup owners paying for heavy trucks’ wear and tear.”
