The New York Times opens up the code and data that generates their Senate forecasts

The New York Times is taking a crack at forecasting the results of the upcoming Senate races. They're currently predicting a tossup, but we don't have to just take their word for it. The code and data that runs the election-forecasting model is open to the public!

The model is built with R, a programming language for statistical computing. I'd love for somebody with some R knowledge to write an article that walks through the codebase explaining how it all fits together. Ping us if you're up to the challenge...
