WATCH: Campaign Ad Shows Siblings Of Sitting Republican Begging Citizens To Vote For The OTHER Guy. Congressman Responds.

You thought you had family drama? Try this on for size: An Arizona congressional ad for Democrat candidate Dr. David Brill features six brothers and sisters of Republican Paul Gosar, the incumbent representative and Brill's opponent in the race, begging citizens to cast their ballot against their brother and for Brill.

The ad, aired on Friday and entitled "A family defends its honor," shows Gosar's siblings -- Tim, Jennifer, Gaston, Joan, Grace, and David -- delivering disparaging remarks about Gosar and his agenda. The ad takes a stark turn when you find out the pro-Brill folks are actually Gosar's brothers and sisters.

"Paul Gosar the congressman isn't doing anything to help rural America," says Grace at the start of the ad.

"Paul's absolutely not working for his district," asserts David, before his brother Tim adds, "He's not listening to you and he doesn't have your interest at heart."

"Paul Gosar's my brother," reveals Grace, as each sibling follows in identifying themselves.

"I endorse Dr. Brill," says one sibling enthusiastically. Another adds, "whole heartedly."

Brill, who's looking to unseat the representative from Arizona’s 4th Congressional District this November, appears at the end of the ad to endorse the siblings' message.

"They feel this is a matter of civic duty, making their public statements even more compelling," Brill said of the ad via a statement.

"I greatly appreciate and admire the courage of the Gosar family in stepping into the national spotlight for this vital message," he added. "We all must honor their dedication of working to build a better future for all Americans. This is a commitment I believe in and will fight for."

Gosar, a heavy favorite who's held the seat since 2013, reacted to the ad via Twitter, writing, "My siblings who chose to film ads against me are all liberal Democrats who hate President Trump. These disgruntled Hillary supporters [sic] are related by blood to me but like leftists everywhere, they put political ideology before family. Stalin would be proud."

In a subsequent tweet, Gosar wrote, "You can’t pick your family. We all have crazy aunts and relatives etc and my family is no different. I hope they find peace in their hearts and let go all the hate," adding, "To the six angry Democrat Gosars—see you at Mom and Dad’s house!"

And, most importantly, the Republican has the approval of his mother, who said she was "crushed" and "shocked" by the ad of her other children targeting Gosar. "I share the same philosophy and policies that Paul does. He’s done a hell of a job for Arizona, and they love him," she told The New York Times.
