My 90 year old father, a life-long Republican until 1992 and Obama supporter since day 1, called me excitedly tonight saying CNN just called the nomination for Obama.

He said, “this is historic” and he’s right. An African-American man is now the Democratic nominee for president and quite probably will become president.

Someone on Twitter said, so now we hold his feet to the fire like any other politician, right? Absolutely. But let’s appreciate this historic moment for the extraordinary moment that it is.
