During the post-2008 election period Silver devoted attention to developing some tools for the analysis of forthcoming 2010 Congressional elections, as well as discussing policy issues and the policy agenda for the Obama administration, especially economic policies. He developed a list of 2010 Senate races in which he made monthly updates of predicted party turnover.

Following a number of preview posts in January and February, Renard Sexton examined subjects such as the UK polling industry and the 'surge' of the third-party Liberal Democrats, while Silver, Sexton and Dan Berman developed a seat projection model. The UK election was the first time the FiveThirtyEight team did an election night 'liveblog' of a non-U.S. election. In April 2010, The Guardian published Silver's predictions for the
