I participated in and witnessed the most transformational moment in the history of US politics --- Barack Obama was elected as the 44th, and the first African-American President of the United States last night. As he put it in his victory speech in front of around 125,000 people gathered in Chicago's Grant park, "If there is anyone out there who doubts that America is a place where anything is possible, who still wonders if the dream of our founders is alive in our time, who still questions the power of our democracy, tonight is your answer." I have never seen America be so alive, full of new hope on TV for my last 16 years here. The cheering, the feat, the exuberating atmosphere I saw on TV last night, I have only seen it once in the ending scene of the blockbuster movie "Independence Day" when earth defeated aliens.  New York Times with triple bold font title declared "Racial Barriers Fall as Voters Embrace Changes." Several TV commentators wept, General Colin Powell wept. Among the crowd in Chicago, there is Rev. Jesse Jackson whose eyes glared with tear. He had marched with Dr. Martin Luther King, Jr., in those civil right action days during the 60s.  Obama's victory is only 45 years after Dr. King's "I have a dream" speech, which inspired me a bunch when I read it the first time in 1987 from my English course in Taiwan. While Dr. King's hope in that historical speech was modest (but unthinkable in his times), which he wished "my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character," he would probably never imagine that a black President is to be elected by this nation in a democratic way receiving unprecedented support from the mainstream and it happens only less than half-a-century from the time when black was still segregated in certain Southern states.  It is beyond description to watch and witness this great day's coming and marking the history. After the glory, it will soon come the reality for him to solve all the financial, diplomatic, social messes at this difficult time. The final quesiton is: will Barack Obama become one of the greatest Presidents in the US history? Indeed, he has the opportunity to become one as the greatest Presidents always emerged in the most difficult time in history. I strongly believe in the new President's (and our own) audacity of hope to reclaim many of us' American dreams.
