With the exception of one outlier poll this week, Rep. Kyrsten Sinema, D-Ariz., has mostly enjoyed a small lead over her Republican opponent in the race for the seat of retiring Sen. Jeff Flake, R-Ariz. And again, with the exception of that one poll, she seemed to be one of the few Democratic Senate candidates not suffering from the post-Brett Kavanaugh surge that Republicans have elsewhere enjoyed.

The Arizona race remains close. So will this video, tweeted out by the conservative Reagan Batallion account, of a 2011 speech to the Texas Stonewall Democratic Committee prove to be her undoing?

Sinema's comedic routine included an offer of advice on how "to stop your state from becoming Arizona."

"Over the past several years, people would watch what's going on in Arizona and be like, 'Damn, those people are crazy,'" Sinema says in the video. "Is it something with the water?" she asks, and then answers her own question: "No, the water's fine, we stole it from Colorado." That line got some especially hearty laughs.

She then shares a more extended riff about how Arizonans are nuts. Not a little bit crazy, mind you, but infected with a serious case, such that "crazy" is the state's sixth "C" after cattle, copper, citrus, cotton, and climate. That one drew more modest laughs.

Arizonans might not find it funny at all. Time will tell.
