That statistic about DC does nothing to support your case. DC has just 3 electoral votes out of 538. Their votes in no way reflect the entire country. Also, DC is incredibly liberal and ALWAYS supports the Dem candidate with about 90% of the voters. You would have been much better off to reference the 365 electoral votes Obama got compared to McCain’s 173.
He write about DC the state where plenty of American bureaucrats reside. They have way more of influence than 3 electoral votes.
