During a Senate Judiciary hearing Thursday, things got tense in a heated exchange between Sens. Dianne Feinstein (D-Calif.) and Ted Cruz (R-Tx.). When Cruz tried to point out the constitutional implications of Feinstein’s gun control proposal, the California Democrat accused him of talking down to her like a “sixth grader.”

WATCH:

Just one day later, the Democratic Party is trying to use the back-and-forth to their own advantage in an emailed fundraising plea to supporters:

“Cruz is setting new records for crazy,” the Texas Democratic Party chairman, Gilberto Hinojosa, wrote today in an email to potential donors. “If Cruz and his crazy don’t represent you, DONATE TODAY to support our efforts.”

He noted that Feinstein has an all-too personal history with gun violence, reminding readers of his email that she “became mayor of San Francisco after Harvey Milk and Mayor Moscone were shot and killed in City Hall. She saw their bullet-riddled bodies. She broke the news to the public. She has sat on the Senate Judiciary Committee for twenty years. Cruz decided he needed to give her a lecture to explain the Constitution and guns. Republican Joe Scarborough gave a fierce and impassioned response to Cruz’s lecture, calling it, among other things, `complete and utter ignorance.’ ”

You know an argument is totally legit when it comes from Joe Scarborough.
