The U.S. Supreme Court appears to be on the verge of permitting a huge change in the mix of money in American politics.
Based on the comments from the justices today during an unusual summer argument session, the court appears to be inclined to strike down decades of federal laws and court decisions that have limited who can buy political campaign ads. At stake are laws that ban corporations and labor unions from spending their own money to run ads that attack or support candidates, and ads that even mention a candidate's name in the months leading to elections.
The conservative backers of the "Hillary: The Movie" documentary argued today that the laws are a violation of free speech, and at least five justices appeared today to agree.
