Earlier this week, former Utah Governor Jon Huntsman introduced an ambitious economic plan, including an income tax overhaul that would create a flatter, fairer and more efficient tax code by eliminating all income tax deductions and creating three relatively low rates. Like other GOP candidates he also called for repeal of the Dodd-Frank and health care reform laws, adding part of Sarbanes-Oxley for good measure. Huntsman has not (yet?) impressed GOP primary voters — and I’m still not sure what to make of him — but the WSJ editorial board was impressed, calling his plan “as impressive as any to date in the GOP Presidential field, and certainly better than what we’ve seen from the front-runners.”
