Interestingly enough, Steven Spielberg - a guy who could only be described as a liberal - has one of the largest Rockwell collections in the country (maybe the world).
Other than Rockwell, there aren’t too many other 20th Century American painters I really care for, except for maybe Grant Wood and Ed Hooper. Jackson Pollack, Jasper Johns, Andy Warhol - none of them appeal to me.
Dirty little secret is that Rockwell (once shunned as pedestrian art) is experiencing a revival among the wealthy...especially Leftists.
Winslow Homer. My favorite American artist.
Maxfield Parrish. Exquisite.
