This may become the most important case argued before the Supreme Court this year. The case is Citizens United v the Federal Election Commission.
The case is essentially about whether corporations have first amendment speech rights and whether these were violated when a documentary critical of Hillary Clinton was not allowed to be shown before primary elections last year. The court seems poised to reverse years of precedence stating that such advertising can be limited.
Here's a bit from the NYT:
There seemed little question after the argument in an important campaign finance case at the Supreme Court on Wednesday that the makers of a slashing political documentary about Hillary Rodham Clinton were poised to win. The open issue was just how broad that victory would be.
