Progressives hate the Supreme Court decision on Citizens United and the rise of Super PACs. George Will asks a couple of interesting questions.

Critics of super PACs — critics who were remarkably reticent in 2004 when George Soros was lavishing his own money on liberal advocacy — often refer to them as “outside groups,” much as Southern sheriffs used to denounce civil rights workers as “outside agitators.” 

Pray tell: Super PACs are outside of what? Is the political process a private club with the parties and candidates controlling membership?
