The Michigan primary was a significant victory for Joe Biden, labeling him the presumptive nominee. Still, the night before the election, they had to deal with an incident that was initially labeled as just another “Biden gaffe,” but it might have actually been beneficial for the campaign.

It was a proper altercation, complete with some charming profanity-Biden argued with a Detroit autoworker after the latter accused Biden of “actively trying to end our Second Amendment rights.”

“You’re full of s–t,” Biden told the autoworker Tuesday during a tour of the Fiat Chrysler auto plant on Michigan’s primary voting day. “I support the Second Amendment.”

Biden said he favors gun rights but believes there have always been limits to the Second Amendment, such as how the First Amendment right to speech also has necessary restrictions stopping people from irresponsibly yelling “fire!” in a crowded theater.

“I have a 20-gauge, 12-gauge. My son’s hunt,” Biden said. “I’m not taking your gun away at all.”

The autoworker was adamant, however, and claimed he saw a “viral video” where Biden appeared to be calling for a ban on guns.

“I did not say that,” Biden said. “It’s like the other viral videos they’re putting out that’s a lie.”

Biden has repeatedly been the subject of misleading videos on social media. President Trump himself shared a deceptively edited video suggesting Biden endorsed Trump this past weekend, removing the second part of a sentence about negative attacks against fellow Democratic candidates. “We can only re-elect Donald Trump if, in fact, we get engaged in this circular firing squad here. It’s gotta’ be a positive campaign.”

“You’re working for me, man,” the worker later says in the exchange.

“I’m not working for you,” Biden said. “Give me a break, man. Don’t be such a horse’s a–.”

While some thought that cussing out a potential voter is campaign trail folly, many thought that the incident made Biden appear passionate.
