Election season is heating up and Larry J. Sabato’s Crystal Ball is the place to go for the Web’s most reliable source of political analysis. (The Pew Research Center and the Pew Charitable Trusts’ Project for Excellence in Journalism noted in 2006 that the Crystal Ball “came closer than any other of the top ten potential predictors this cycle.”) Run by UVA’s Center for Politics, this site covers it all: presidential elections, and congressional and gubernatorial races.
