One of the key improvements of the new SCOTUS dynamic is campaign finance reform, revisited. In a pivital ruling yesterday, the court decided to err on the side of free speech, and allow the public to voice their views (views that aren't even endorsing a candidate) on air.
The decision was split 5-4, with Roberts, Alito, Thomas, Scalia, and Kennedy in the majority, Alito and Roberts alined together with Roberts' majority decision; and Scalia, Thomas, and Kennedy writing an additional majority decision, objecting to the fact that Roberts and Alito didn't explicitly overrule the court's 2003 McConnell decision.
While largely viewed as a victory for "corporations," the true winner is the people--and the rule of law. Free speech may not be entirely supressed by McCain-Feingold, yet.
