The problem with the gasoline tax in Virginia can be solved in a way that would not cause periodic political stress for the state’s lawmakers [“Will Mr. McDonnell fight?,” editorial, Dec. 12].

The price of gas may fluctuate over short periods, but it will creep up over the long haul. What we need is an ad valorem tax, like a percentage-based sales tax, rather than a per-gallon assessment.

Once such a tax is approved, politicians would be relieved of having to periodically review it to assure that it is an appropriate portion of the price of gasoline.
