John Stossel on Why Campaign Spending Doesn't Cause Corruption

The Supreme Court right now is revisiting campaign finance laws because Montana's Supreme Court ruled that Montana can ban corporate spending on state politics. Sens. John McCain and Sheldon Whitehouse filed a friend-of-the-court brief claiming that allowing corporate speech would bring a "strong potential for corruption and perception thereof." Right, says John Stossel, as though politicians don't routinely constitute a "potential for corruption" all by themselves.
