Two quotes from the US press emphasise the awesome, historic nature of Obama's victory:
Los Angeles Times:
Barack Obama, the son of a father from Kenya and a white mother from Kansas, was elected the nation's 44th president Tuesday, breaking the ultimate racial barrier to become the first African American to claim the country's highest office. A nation founded by slave owners and seared by civil war and generations of racial strife delivered a smashing electoral college victory to the 47-year-old first-term senator from Illinois, who forged a broad, multiracial, multiethnic coalition. His victory was a leap in the march toward equality: When Obama was born, people with his skin color could not even vote in parts of America, and many were killed for trying.
America's election of an African American as president wasn't the only breakthrough Tuesday night. By defeating John McCain in such reliably Republican states as Colorado and Virginia -- capital of the Confederacy and a state that hasn't backed a Democrat for president in four decades -- Barack Obama reshaped the electoral map that has defined American politics for a generation.
