Political scientists say we choose presidents based on looks

We all want to know what each presidential candidate stands for, but let's face it, sometimes politics can be so boring.

When you pick your candidate, it's often about something a lot simpler. Political scientists says sometimes it just boils down to a looks contest.

A study from Princeton University showed people random photos of people who ran for the House and Senate in 2004.

Take a peek at the 2016 presidential candidates still in the race:

With just a look at their face, not knowing anything about their party, policies, or anything else, people were able to guess the winners nearly 70% of the time.

We've seen it work in real life too. The first televised presidential debate put John F. Kennedy against Richard Nixon. The people who listened to the debate on the radio thought Nixon won, but people who watched on TV and actually saw JFK flash that winning smile said Kennedy was the clear winner.

So, what is that "it" factor that makes someone look like a winner? Studies show a round baby face, with strong cheekbones, and arched eyebrows makes a person seem trustworthy.

If you're trying to figure out who will set up shop in the White House, quit worrying about the race and take a look at the face.

But the most attractive doesn't always win. Sorry, Martin O'Malley.
