Campaigns and political action committees have pumped millions into the Louisiana governor’s race over the past two months.

According to The Advocate’s analysis of campaign finance reports that were due Thursday, candidates and PACs spent more than $6 million between July 18 and Sept. 14.

U.S. Sen. David Vitter, Lt. Gov. Jay Dardenne, Public Service Commissioner Scott Angelle, all Republicans, and Democratic state Rep. John Bel Edwards are the four major candidates for governor this year. The election is Oct. 24 with a Nov. 21 runoff, if no candidate gets more than 50 percent of the vote the first time around.

Vitter, who has maintained a strong money lead throughout the race, has maintained that edge and has the most left to spend in the campaign’s final stretch.

His formal report had not yet been uploaded to the state Ethics Board website late Thursday, but his campaign announced that he has more than $4 million left in his campaign coffers.

Dardenne’s campaign, meanwhile, reported having $1.62 million cash on hand, followed by Edwards with $1.38 million and Angelle with just over $1 million.

For the most recent reporting period, Edwards raised the most with $841,974 in cash and in-kind contributions, followed by Vitter with $838,256, Angelle at $619,962 and Dardenne at $376,345.

This year’s race has seen an infusion of spending from outside groups seeking to boost or diminish various candidates’ chances.

The pro-Vitter Fund for Louisiana’s Future raised $138,276.40 during the reporting period and spent $1.41 million. The biggest single donation — $50,000 — came from a Florida-based dental benefits administrator. The fund had $3.1 million left heading into the final stretch of the election.

Louisiana Rising PAC, which is backing Angelle, raised $1.1 million — $1 million of that from Texas oil and gas executive James Flores. The PAC spent $233,694 last period, and ended with $1.1 million left.

And the pro-Dardenne Now or Never PAC has mostly depleted its resources after spending $150,914 during the reporting period. It reported $8,911 on hand.

Two groups that have targeted Vitter spent more than $850,000 on their efforts over the past two months — much of that through the Louisiana Water Coalition, which has run TV and radio ads across the state against Vitter.

That group revealed for the first time the source of its funding: Talbot, Carmouche & Marcello, a Baton Rouge law firm that has taken on several environmental cases, including Jefferson Parish and Plaquemines Parish wetland cases versus oil companies.

The other group, GumboPAC, reported just $12,416.67 in donations for the reporting period, but reported a large infusion of cash — mostly from law firms — in a report that was filed last month, after the last deadline.

GumboPAC reported $84,628.54 cash on hand heading into the final stretch, while the Water Coalition PAC ended the reporting period with $304,259 cash.

Now or Never also accepted $5,000 in research from GumboPAC, the records show.
