This morning I was reading an interesting section dedicated to the US elections on the FiveThirtyEight site. It tries to predict who will win the election based on the polls and historical data. They have been very accurate in the past, so it is definitely an interesting source.

One of the articles linked on this site was a post titled "Why Obama Might Be Trump's Biggest Challenge," which discussed how President Obama is enjoying a high approval rate. The chart above is generated with the RealClearPolitics data they mentioned in the post.
