I remember Maher way, way back in the early days of his talk show shtick, back on the now-defunct Comedy Channel. Back then (this is late 80s to very early 90s) he was much more libertarian than leftist. He was still a jerk, of course. But he wasn’t the frothing blowhard he’s become since those days. Perhaps he’s rethinking a thing or two these days and seeing the light on a few issues.
I mean, I wouldn’t bet on it, but it’s possible.
Comedy Channel is not defunct, it is still around apparently
