A bitterly divided Supreme Court ruled on Thursday that the government may not ban political spending by corporations, labor unions or other organizations in elections. The court’s majority in Citizens United v. Federal Election Commission swept aside a century-old doctrine in election law, ruling that the campaign finance restriction violated the First Amendment’s free speech principles. The dissenters said opening the floodgates to corporate money will corrupt democracy.

Rep. Alan Grayson (D, Florida) says it's the most irresponsible Supreme Court decision since Dred Scot.
