Are Jill Greenberg's manipulated images of Senator John McCain eye-catching and provocative? Without doubt, and that frankly is the first thing that visual political satire must be.
Are they particularly clever or sophisticated. I don't think so.
Will they cause anyone to vote for Barack Obama? Perhaps the very opposite.
Do they represent something immoral--what one commentator has called "political pornography?" No. They're too silly for that. That's weirdly part of the charm of Greenberg and her work.
But there are some questions that need to be answered about these pictures, and they may have an impact on how photographers go about their work in the future.
