No, he hasn't. He changed his party registration SIX times, he's given lots of money to liberal Democrats, he said a few years ago that he identified more as a Democrat, that the Republicans are just too extreme (and dumb, BTW -- that he could fool them), that he supported the stimulus. He praised 0bama, Hillary, DeBlasio, and others. He has endorsed the individual mandate and touchback amnesty.
Conservative? It doesn't look that way to me.
Gotta put on your orange-colored Trump glasses. Then you’ll see the conservatism. :-)
