lol... moderate and liberal
Republicans. The "Democrats" who supporting him are Southerners who vote Republican, and are still registered as Democrat -- which means in many cases, they can't vote in Republican primaries. Many of his supporters don't usually turn out for elections anyway. (See

He's drawing from disaffected Republicans, not people who are on the left side of the spectrum.
Nativism, birtherism, authoritarianism, sexism, borderline racism, pro-gun, defunding Planned Parenthood (yes, he's now anti-abortion), debt fear mongering, cutting Department of Education, climate change denialism, attacking EPA, anti-regulation, anti-ACA (with no replacement plan), Islamophobia, against minimum wage hikes, censoring Internet... All recent Trump positions. These are not leftist positions.
Top it off with looking to the past with rose-tinted glasses, to appeal to the (white) people who have gotten the shaft. Political nostalgia with a coat of whitewash is the domain of conservatism... if not a key part of its self-identity.
Whatever he said in the past, he has clearly moved to the
right, not the left, in order to appeal to Republicans.
You can shout all you want that he's not a "real" conservative and/or a RINO. No one cares. He's a GOP mess, not a leftist one.
