The underlying theme of the GOP race this year seems to be Citizens United, observes Law.com. The Supreme Court decision that led to the creation of super PACs funded by unlimited donations is getting its first real-world test, and the results are hard to miss. Most notably: The super PAC known as Restore Our Future decimated Newt Gingrich with negative ads on behalf of Mitt Romney. As Politico notes, Gingrich called the decision at the time a "great victory for free speech," and while he still supports it, he is also complaining about being "Romney-boated" by his rival's "millionaire friends."
