Is Bernie a one-trick pony? Kinda, and that's why I question whether he'd be a good president. But that's okay in a presidential primary. He's stumping consistently on a few issues that matter to his base, issues Hillary has been weak on for years. And Bernie being in the race is good for Hillary. If Bernie conceded today, all press coverage would shift to the GOP sideshow and Hillary would go dark until the convention. That's a losing situation for the Democratic Party as a whole. There's nothing immoral about stumping on what you believe might help America, provided you do it in a respectable, presidential manner... And Bernie has done just that. He's trying to steer the conversation toward his issues and has done a respectable job of accomplishing his goal. And he's doing it entirely on private donations, which means his message resonates with a large group of Americans. In today's lobby-centric political machine, I don't see how anyone can view that as a bad thing. People are acting as if Bernie has 150 delegates. Proportionally speaking, he's closer to Hillary than Cruz is to Trump, yet no one is calling for Cruz to bow out of the race.
