New Jersey Gov. Chris Christie just took a big fat step toward running for president

New Jersey Gov. Chris Christie and his supporters have formed a political action committee ahead of a likely bid for president, Reuters reports. The PAC, called Leadership Matters for America, is "the clearest sign yet that Christie, 52, is running in the Republican Party primary for the 2016 presidential election." + While we're starting in on our 2016 reporting (we know, we're barely into the new year), let's get one thing out of the way: No matter what anyone says, Sarah Palin is not serious about running for president — just watch this bizarre video. + Meanwhile, conservative billionaire brothers Charles and David Koch and their network of private donors are planning to spend nearly $900 million to support select Republican candidates in the 2016 election cycle, more than double what they spent in 2012.
