Donald Trump made a horrible misstep when he diluted his position on deporting illegal aliens. It’s been one of the primary reasons that he’s been as successful as he has as a first-time candidate. He seems to have corrected course (mostly), but he’s done his brand some lasting damage. I don’t believe that he can withstand making that mistake again. No matter what the media and the two political parties tell you, this election is all about the specific issues that Donald Trump has put forward — it’s not about the likability or popularity of either candidate.
