I tend to agree, but to a point. Politics and aesthetics are enmeshed - there is a reason why, say, the painting by the Viennese painter Gustav Klimt http://vortex1.no-ip.com/klimt/ were judged to be the "degenerate art" by the Nazis, even though they are conspicuously apolitical. Most of it is landscape and human body - but shown in a way that is absolutely repulsive to those who enjoyed the aesthetics reveals in the Triumph of the Will or, for that matter Aleber Speer's architecture http://www.dataphone.se/~ms/speer/welcom2.htm.
"Good" political content can have bad artistic expression, and vice versa, but ultimately art and politics can be linked to the cognitive and personality characteristics of individuals, and thus are correlated (albeit not perfectly). Authoritarian types tend to have preference for authoritarian aesthetic, nurturing types tend to have preference for nurturing aesthetic, of which Klimt and Cramer vs. Cramer can be good examples. No coincidence that authoritarians despise both. Progressives tend to be more open minded and do not reject a work of art solely on its political contents, but I think subtle preference is there.
