Louisiana residents may feel like they are being inundated with campaign ads heading into Saturday’s election.

It’s probably because they are, based on a new analysis from the Center for Public Integrity.

TV campaign advertising in this year’s elections has reached nearly $15.8 million since January 2014 — more than any other state this cycle.

The amount is equal to about $4.70 per every potential Louisiana voter, CPI notes.

The race to replace Gov. Bobby Jindal has made up nearly two-thirds — $10 million — of the advertising blitz, with Republican U.S. Sen. David Vitter and groups backing him leading the pack.

Vitter faces Democratic state Rep. John Bel Edwards and Republicans Public Service Commissioner Scott Angelle and Lt. Gov. Jay Dardenne.

Vitter has aired nearly twice as many ads as Angelle, who has had the second-most ads.

About $1.7 million has been spent in the lieutenant governor’s race. That matchup is between Democrat Kip Holden, who is the mayor of Baton Rouge, and Republicans Jefferson Parish President John Young, former Plaquemines Parish President Billy Nungesser and state Sen. Elbert Guillory, of Opelousas.

Louisiana is one of just three states holding its governor and other statewide elections this year. Jindal, who was first elected in 2007, is term-limited and running for president.

In the past week alone, CPI estimates $3.1 million was spent on political ads — more than half of that on ads that are at least partially negative.

The Center for Public Integrity’s analysis is based on political advertising data from Kantar Media/CMAG, a media tracking firm. The data doesn’t include other forms of advertising, such as radio spots and direct mail.
