It is awful -- cluttered, ugly, and propagandistic. One might as well have a painting of the interior of a slaughterhouse.
Political art has its hazards. If derogatory it has the usual perils of satire even if the message is obvious -- essentially that the Leader doesn't have a clue. Maybe one contrasts potentates living in opulent splendor while the common man suffers. If one has excessive reverence then one might as well paint a religious icon.
I checked the link and found heavy-handed politics with 'artistic' heavy-handedness to match. Anachronisms abound in a piece of 'art' that depicts 'traditional' heroes of America identified with the heroic working people contrasted with the villains of America -- an arrogant college professor who promotes 'godless' science, a liberal reporter out of touch, an attorney selling out justice and the general good for the gain of themselves and their clients, and a Supreme Court justice who has put some legal principle above 'Americanism'... these are the 'wreckers' of all that is good. As for what is 'good' I notice Abraham Lincoln in the 'humble' pose of a theatrical performer accepting applause -- right next to Jesus. Such is blasphemous.
Political art is often the bastardization of art. It often unites people unlikely to meet (let us say coal miners and peasant farmers in socialist realism or research scientists and housewives in capitalist realism), introduces pointless anachronisms (an adult Lincoln next to an adult Washington is a favorite even though Washington died two days short of nine years and three months before Lincoln was born). I'm no artist, but if I were to show any connection between Barack Obama and Abraham Lincoln I would show Obama reading about Lincoln.
I am not an artist, but I can imagine how I would show the hypocrisy of our economic order. Titled, "The Wrong Exit", it shows some stereotype of a rich executive and his family... fifty-something executive with a bleached-blond wife thirty years her junior, with her stepson almost her age 'connected' to a sanitized-but-unreal 'virtual reality', and a stepdaughter in a riding habit having made the wrong turn off the expressway in a luxury-marque SUV and into a modern Hooverville -- in shock and disbelief, seeking directions on how to get back to some desired destination. Maybe I show a drug deal or a low-end hooker, and the couple trying to shield the kids' eyes.
