Washington (CNN) - If you want to understand the historical magnitude of President Obama's re-election victory, start with this fact: He lost the white vote by 20 points. In 1988, Mike Dukakis lost white voters by 19 points. He was crushed in a 40-state landslide.
Obama's victory is a testament to a changing America. The president won a second term in the face of a weak economy by reassembling the bulk of his 2008 coalition: Hispanics, African-Americans, younger voters and single women. Mitt Romney's support was older, whiter, and more Protestant than the president's - a faded shadow of a time gone by.
It also bore a striking resemblance to Sen. John McCain's coalition four years ago.
