Barack Obama was greeted by the largest crowd of his campaign Friday night in Philadelphia. Some 35,000 people jammed into Independence Park to see the Democratic presidential candidate, four days before this state's crucial April 22 primary. Obama told the crowd the United States is at a crucial moment in its history, much like what the founding fathers faced in Philadelphia. "It was over 200 years ago that a group of patriots gathered in this city to do something that no one in the world believed they could do," Obama said. "After years of a government that didn't listen to them, or speak for them, or represent their hopes and their dreams, a few humble colonists came to Philadelphia to declare their independence from the tyranny of the British throne."
