According to "Politico", "Rasmussen's final poll of the 2008 general election—showing Obama defeating Arizona Sen. John McCain 52 percent to 46 percent—closely mirrored the election's outcome." In reference to the 2008 presidential election, a "Talking Points Memo" article said, "Rasmussen's final polls had Obama ahead 52–46%, which was nearly identical to Obama's final margin of 53–46%, and made him one of the most accurate pollsters out there." An analysis by Costas Panagopolous in 2009 ranked 23 survey research organizations on the accuracy of their final, national pre-election polls based upon Obama's 7.2% margin of victory; the analysis determined that Rasmussen Reports was tied for 9th-most accurate. Democracy Corps, Fox News/Opinion Dynamic, CNN/Opinion Research, and Ipsos/McClatchy all predicted an accurate seven-point spread.
