It seems to me that he is a liberal rather than a progressive.
If all of the Democrats were this kind of liberal, this would be a totally different country and Congress would be a worthy place to hash out differences. They aren't and Congress isn't.
Most actual liberals are either dead or drooling all over themselves in nursing homes. Their children and grandchildren (those not aborted, IOW) are mostly a bunch of raving Leftists (I thoroughly dislike the term “progressive,” since the very word is intended to mislead people into a belief about those who are Leftist scum).
