Nate Silver is known for his crunching of polls to determine the likelihood of presidential and senate candidates of winning their seats. He uses current polls along with voting trends in states to determine projections that have been very accurate in the past. With this election season coming to close, it's a website I check daily, and often several times a day, to see how the presidential projections have changed.
Even if you're not a fan of politics, FiveThirtyEight is a great source for statistics in other fields such as sports. Right now there is a feature article on the Chicago-Cleveland World Series currently underway. There's another feature article on the quality of NFL teams this current season. FiveThirtyEight is not so much a political site, but a site that crunches numbers and produces projections in various field. It's just mostly known for its work in politics.
If you love numbers and you love statistics and projections, you'll love FiveThirtyEight. I personally blame Nate Silver for taking up a great deal of my time this election season! LOL!
