S.R. Sidarth - the person that George Allen called "macaca" - provides his post-election perspective of the incident and more:
The larger question that this experience brings up is: How far has society progressed on the issues of race and openness? By 2050, according to most projections, the United States will be a minority-majority nation. But the fact that Allen believed I was an immigrant underlines the problems our society still faces.Webb's victory last week gives me hope that Virginia will not tolerate playing the race card. It is still hard for me to accept that I could have had a pivotal role in the election results; I would not wish the scrutiny I received on anyone. But I am also glad to have helped Webb. Every little bit counted, especially in an election decided by about 9,000 votes out of nearly 2.4 million cast.
The politics of division don't work anymore. Nothing made me happier on election night than finding out the results from Dickenson County, where Allen and I had our encounter. Webb won there, in what I can only hope was a vote to deal the race card out of American politics once and for all.
Also, Sidarth makes clear that the incident did not reflect the treatment he received from Southwest Virginians:
Everywhere I went, though I was identifiably working on behalf of Allen's opponent, people treated me with dignity, respect and kindness. I cannot recall one event where food was served and I was not invited to join in the meal. In southwest Virginia, hospitality toward me was at a high point.
Go read the entire thing - it's well written and provides important context and meaning to the incident that turned the race upside down.
