Playing to the batshit insane

It's all clear now. John McCain is attacking Barack Obama with bullshit faux outrage about the crazy rightwing extremists trying to recruit vets because of primary opposition in 2010 from crazy-eyed wingnut and immigration militiaman Chris Simcox.

When running in a Republican primary, it's always useful to appear as batshit insane as possible. That's known as playing to the base.
