In Louisiana's 5 th District Congressional race, one of the most coveted political endorsements comes in the form of a "duck call."

That's because the 5 th District is home to the "Duck Dynasty" clan made famous through the A&E reality show.

And this year, the clan has swooped in to support Republican candidate Zach Dasher, a family member, in his bid to replace the "Kissing Congressman" Rep. Vance McAllister, also a Republican.

A week before Election Day, the patriarch of the family clan and Dasher's uncle, Phil Robertson, is starring in two new TV ads on Dasher's behalf.

"On Tuesday, Miss Kay and I are voting for Zach Dasher," Robertson says in one ad. "He loves his family, he's got a servant's heart, he knows his Bible. He is a good man. We vetted him."

In addition to the new TV ads, 80,000 Louisianan phones received robocalls from Uncle Si, another family member of Dasher's who also stars in the popular TV series.

"We need to elect a man that totes the Bible and believes in God. That's what this country was founded on - God and the Bible," Si said in the call. "There's a war going on. If you doubt that, look what's going on in Houston, Texas, all right?"

The calls were paid for by the tea party group Madison Project.

The heavy involvement of the Duck Dynasty clan in backing Dasher stands in contrast to the family's endorsement for McAllister just last year, when the self-made millionaire and political newcomer swept to victory in a special election to fill the vacated seat of former Rep. Rodney Alexander. His victory was thanks in part to the endorsements from the Robertson clan.

The Robertson's broke with McAllister earlier this year after the release of a surveillance video that showed the married congressman kissing a woman who was not his wife. That scandal earned McAllister the "kissing congressman" nickname.

How consequential the Robertson endorsement will be to the race has yet to be seen.

There are a handful of opponents, in addition to Dasher, challenging McAllister for the seat, and the race has not maintained a clear frontrunner.

It's also possible voters won't know the final results of the race until December because of Louisiana's non-partisan "jungle primary" system. If no one candidate receives over 50 percent of the vote on Nov. 4, the election will proceed to a runoff in December between the two candidates with the most votes.
