According to the Arkansas Democrat-Gazette, the average Arkansas tax burden increased 47% over Huckabee’s tenure. Huckabee supported (in chronological order) a sales tax hike; gas and diesel fuel tax hikes; another sales tax hike; a cigarette tax hike; a nursing home bed tax; another sales tax hike; an income surcharge tax; a tobacco tax hike; taxes on Internet access; and higher beer taxes. Huckabee also oversaw a 50-percent increase in spending; happily signed a minimum wage increase and encouraged national Republicans to do the same; favors a national smoking ban, farm subsidies, and a federally mandated arts and music curriculum; opposes private school choice; and employs class-warfare and protectionist language on the campaign trail. Huckabee calls himself an economic conservative in the mold of Ronald Reagan, but the above list doesn’t sound like either.
The CATO group rates Huckabee as an F in his final term regarding raising taxes.

Factcheck.org also rates Huckabee poorly on the tax issue
