Perhaps no presidential candidate has the self-confidence he does, even in the face of some glaring flip-flops on his political positions. Where lesser candidates would dodge questions about why they've changed their mind or give a focus-group-tested line about how they evolved, Trump doesn't admit to ever having a different opinion.He loved Hillary Clinton; now he thinks she's the worst. He was very much in favor of abortion rights before he opposed them. And he might be running as a Republican today, but he was once a registered Democrat who called for legalizing drugs, a massive one-time 14.25 percent tax on the wealthy and staying out of wars that didn't present a "direct threat" to the U.S. In many ways, he's been to the left of Clinton and even Bernie Sanders on some issues.
