He's a socialist, not a communist, still garbage but not pure garbage. You're right about the debate part though, have you seen him with Hillary? Lmao.
But lets be honest here, it's not that Bernie has trash debating skills that is leading to him losing the nomination to Hillary, the system's corrupt, the system prefers Hillary, there has been states he has won but much of the delegates were still handed to Hillary.
Also, be patriotic but not nationalistic, makes us look bad.
