The 2016 US election has been fought in cyberspace as much as on the stump.
Now that the campaigning has finished, attention turns to the results. CBR offers guides to the key twitter accounts and blogs, the biggest online only news streams, the mainstream media online presence and social accounts and the best analytics and data sites.
538 is a one-stop shop for election predictions, figures and analysis.
The site is powered by a methodology devised by economist and writer Nate Silver.
As well as taking into account the results of polls themselves, Silver also weighs polls according to their quality or how historically accurate the poll has been.
He also factors in information such as economic conditions.
Although widely referenced, the model is somewhat controversial and has been criticised by some pundits. However, Silver has been successful in predicting the last two US elections.
The site also offers a similar service for baseball.
