RealClearPolitics
RealClearPolitics (RCP) is a Chicago-based political news and polling data aggregator formed in 2000 by former options trader John McIntyre and former advertising agency account executive Tom Bevan. The site's founders say their goal is to give readers "ideological diversity". This claim has been disputed by Daily Kos, alleging observations of a conservative bias. However, AllSides Bias Rating is "Center".
RCP has expanded to include a number of sister sites. Politico executive editor Jim VandeHei has called the site "an essential stop for anyone interested in politics".
