So much for Joe Biden's "No Malarkey" tour of Iowa -- there was plenty of it when he got into a heated argument with a voter Thursday morning.
The Democratic candidate was holding a town hall meeting in New Hampton, IA ... when an attendee stood up and challenged Joe on his son, Hunter Biden's now infamous dealings with a Ukrainian gas company.
The man suggested Joe was no better than President Trump because he had placed Hunter in a position for which he wasn't qualified -- and Biden immediately stepped to the guy, barking, "You're a damn liar!" He got right in the guy's face and then challenged him to do push-ups, go for a run or take an IQ test. You gotta see it ... it's kinda bizarre.
Biden, who's in the middle of an 8-day, 18-county swing through Iowa -- which he's deemed the "No Malarkey" tour -- demanded the potential voter get his facts straight.
