The Arkansas Leader debates the supermajority requirement

The Arkansas Leader's latest editorial takes up the severance tax (as it pertains to natural gas). It ends with a theory that a simple majority should be sufficient for a modest increase in the tax:

Here is our reasoning for the majority vote: The state Constitution says that it takes a three-fourths vote of each house to raise the rate of a tax that existed in 1934. At that time, the tax rate on gas was 2.6 percent of its wellhead value, not three-tenths of a penny. So a simple majority of the legislature ought to be able to raise it to 2.6 percent again although it would take a three-fourths vote to raise it higher.
