Henry Winkler holds his "Happy Days" co-star Scott Baio in high regard despite their opposing political views. It's been over three decades since Winkler took on the role of Arthur "Fonzie" Fonzarelli, the doting older cousin of Charles "Chachi" Arcola (Baio) in the beloved ABC show about the Cunningham family, which ran from 1974 to 1984. The two sitcom stars had the opportunity to reunite with the rest of the cast at a Democratic fundraiser held in Wisconsin in October.
