Donald Trump is making noise about an independent bid for president. If the Republican National Committee doesn’t treat him fairly, Trump says, he’ll be more likely to launch a third-party run. I don’t know if he is at all serious, but I do know two things: History suggests that an independent Trump campaign would crash and fail; polling suggests that even if that happened, Trump could take the Republican candidate down with him. CONT.
