BATON ROUGE (AP) - A conservative group that helped squelch a 2017 proposal to raise Louisiana's gasoline tax is launching an early ad campaign aimed at derailing any similar tax proposal next year.

  

Americans for Prosperity-Louisiana, funded by the Koch network, says its campaign will use Christmas-themed videos shown on gas pump screens at heavily-used stations in Louisiana's urban areas.

  

The Advocate reports that digital ads also are planned.

  

Any legislative efforts aimed at increasing the gas tax are expected to be nearly impossible to pass next year, in a statewide legislative election year. But supporters of more road and bridge money still are seeking the tax hike.

  

Gov. John Bel Edwards' administration proposed a 17-cent-per-gallon increase last year, but the measure died without a vote in the House, unable to pass amid strong opposition.
