Following his acknowledgment of the bravery and sacrifice of his opponent, Sen. John McCain, Obama used his speech as a call to action.

He relayed a story of a 106-year-old voter from Atlanta. From the Depression to World War II, from Civil Rights to the current financial crisis – America has seen tough times before. Today, once again, she got to vote for change.

Obama moved the crowd in Chicago and moved Americans across the country.

The crowd answered Obama’s call to action with a ubiquitious “Yes We Can.”
