Today’s generation of grassroots political commentators may not have its marches on Washington ala the Vietnam era, but it does have its own unique form of commentary which has been enabled by all the cheap audio and video editing software that’s out there and the ability to distribute the resulting product via the internet.

A great example is what a guy who’s dubbed himself DJ RX has done with a mix or "mashup" of President Bush singing U2’s Sunday Bloody Sunday, which you can listen to here.

Genius.
