More on the politics of Jared Loughner, via a leaked Department of Homeland Security memo obtained by FOX News:

Strong suspicion is being directed at AmRen / American Renaissance. Suspect is possibly linked to this group. (through videos posted on his myspace and YouTube account.). The group’s ideology is anti government, anti immigration, anti ZOG (Zionist Occupational Government), anti Semitic. Gabrielle Gifford is the first Jewish female elected to such a high position in the US government. She was also opposite this group’s ideology when it came to immigration debate.

The question remains: To the extent that Jared Loughner has a coherent right wing political philosophy, where did it come from (there are reports that he used to be left leaning), and did this political philosophy become part of his internal justification for the actions he allegedly took yesterday?
