Why don’t Americans care more about campaign finance reform?

At the same time, Americans are not well versed in campaign finance law. Just 40 percent correctly identified what a Super PAC was in a Washington Post-Pew Research poll last year, and 51 percent thought increased spending from outside groups would not help Barack Obama or Mitt Romney more in their quest to win the 2012 presidential race. Far fewer, moreover, thought Obama (15 percent) or Romney (16 percent) would gain a distinct advantage from such spending. And when asked in their own words what impact increased spending by outside groups would have on the campaign, just 24 percent described a negative consequence; three-quarters described a neutral impact or had no opinion, while 2 percent saw it as a positive.

I am actually surprised that 40% of people were able to correctly identify what a Super PAC was, that seems pretty high given 2/3 of people can't name a single Supreme Court Justice.
