David Mamet's Village Voice confession that he's no longer a "brain-dead liberal" has caused a bit of a stir.
Well, based on statements he'd been making for a while, I can't say it's much of a surprise. But really, who cares? His importance, such as it is, is based on his art. He rarely writes explicitly political stuff (though his latest is), but even if he did, what would count is the quality of the writing, not what side he's on, or even how well he makes his case.
It will be interesting, however, to see how the theatrical world reacts.
PS I find his unorthodox ideas on acting and directing far more interesting--i.e., actors should say their lines and otherwise shut up and directors...well, let's just get rid of them.
