The Democratic race is heating up, with Clinton leading Sanders by a very small margin. It has divided liberals across the country into Hillary and Bernie camps. But who are the people supporting Clinton and Sanders? Are they neighbors or are they geographically distant? More importantly, are they economically similar, or is there an income gap between them?

We took a look at the zip codes where one candidate most out-performs the other in fundraising - the places where one candidate has raised the most relative to the other.

Other than the Wizard of Oz, tornadoes, and the world's largest ball of twine, most people seldom think much about Kansas -- unless they are on the boring 425-mile trek on I-70 to get somewhere else. Politically, this state is no different. We're a flyover state -- solid red Republican territory that votes too late in the cycle to usually matter.

But since the last mid-term election in 2014, Kansas has been nothing but news politically, from an independent U.S. Senate candidate almost beating the sitting incumbent to allegations of systemic voter machine fraud.

The “three lanes” present in this year’s presidential primary are certainly the perfect storm for the GOP establishment. Today, the GOP elders’ calls to Ohio Governor John Kasich are likely getting more frantic, essentially telling him that he is now the spoiler for Marco Rubio’s chance to take the nomination from Donald J. Trump.

The elders would call Ted Cruz, but they don’t seem to have his number — not to mention that any accusation to Cruz that he is the spoiler would be met with reciprocal derision that Marco Rubio is the real culprit.

2016 is almost certain to be a year that political scientists and historians will study for decades to come. In a presidential election season where one party’s front runner has made forcing Mexico to build a wall to keep undocumented immigrants out a core component of his campaign while a competitive candidate in another party is advocating for free health care/education, it is clear that deep political fault lines have formed.

The death of Supreme Court Justice Scalia may be what causes an actual political earthquake.

Americans love horse races, especially the political kind. News organizations know this, so they make sure to create a horse race or two every four years—even when (and perhaps especially when) a race promises to be a dull ride and a foregone conclusion.

I don’t mind this much. Politics have been a form of entertainment in the United States since the very beginning. This is better than being, as it is in many countries, a blood sport.

Independent voters are the fastest growing voting demographic in the United States. As of the latest registration reports, there are approximately 28 million independent voters registered nationwide. The chart below includes the most recent available data for each state as of mid-January 2016.

Please note that some secretary of state offices do not regularly update this information and not every state offers the option of declaring party preference upon registration. Because of this, it is difficult to determine the exact number of independent voters in those states.
