With the coming presidential elections, it’s important that people be informed about who it is they’re voting for. One part of that is voting for a candidate who knows what he’s talking about.

Fact-checking is a recent phenomenon used to determine how truthful something is. The website Politifact, which has been fact-checking politicians since 2007, has begun to check the 2016 presidential candidates’ statements.

Politifact ranks the statements of politicians on a scale from true, a statement that is accurate, to “Pants on Fire!,” a statement that is not only false but also makes ridiculous claims.

According to Politifact, Republican candidates are much less truthful than Democratic ones, the exception being John Kasich, who is relatively close to Bernie Sanders and Hillary Clinton.

Donald Trump, the Republican front-runner, currently has 77 percent of his statements in one of the false categories, making him the least truthful candidate in the race. Trump’s major appeal is his confidence and his defiance of the system, yet he seems to be wrong  most of the time, with most of his statements about Mexico, the economy and foreign policy being incorrect.

Trump’s main competition for the Republican nomination, Sen. Ted Cruz, is almost as dishonest as Trump is. Currently, only 35 percent of Cruz’s statements are in any of the three truthful categories. Most of Cruz’s truthful statements are either about his own legitimacy or attacks against Trump or current President Barack Obama.

Conversely, the Democratic candidates are usually more truthful. Sanders currently has 70 percent of his statements fall in one of the three true categories while Clinton rates 72 percent.

Despite Clinton’s truthfulness, it should be noted that Clinton tends to change her mind fairly often to reflect the current polls. Clinton has previously flipped on the subjects of same-sex marriage and the Iraq war among others as the polls reflected a change in support.

Most of Sanders’ false statements seem to be exaggerations. Sanders will often cite studies or polls and use the higher estimates—which, though technically legitimate, are unlikely—or he will make somewhat hyperbolic claims in his statements.

While it is important for a candidate’s policies to benefit the nation, it is also important that a candidate tell the truth. People in power need to be held accountable when they lie or misinform the people they are meant to govern; otherwise, they can convince the people to allow radical or detrimental policies.

At this time, when information is so readily available, it is important to be informed this election year.
