BATON ROUGE - A super PAC supporting David Vitter's candidacy for governor has gone on the attack, with a new TV ad slamming the Republican U.S. senator's two GOP competitors. 

The Fund for Louisiana's Future is blasting Vitter's GOP opponents - Public Service Commissioner Scott Angelle and Lt. Gov. Jay Dardenne - as supporting higher taxes.

The 30-second ad is running in Shreveport and Monroe.

The ad criticizes Dardenne for his support of the Stelly Plan, which eliminated some state sales taxes in exchange for higher income taxes on middle- and upper-income earners. The higher taxes have been repealed.

For Angelle, the ad claims he wants to "tax the Internet," because he supports requiring companies to collect state sales taxes on online purchases. People already are supposed to pay those taxes in Louisiana.
