Though modest compared to the hundreds of thousands who greeted him in Berlin last week, the crowd of 35,000 who gathered on an April night on Philadelphia's Independence Mall to listen to Sen. Barack Obama was one of the largest crowds in the state's political history.
Despite that enthusiasm, the scores of thousands of new Pennsylvania voters registered by his campaign and his huge spending advantage, Mr. Obama was clobbered in April by Sen. Hillary Rodham Clinton.
Months later, the Obama campaign believes that spring setback sowed seeds for a November harvest. Indeed, long-term demographic trends and more recent polls and party registration shifts suggest that in November the state is Mr. Obama's to lose.
A Clinton partisan then, but an Obama ally now, Gov. Ed Rendell suggests that the Obama campaign's grass roots efforts may have paid off in ways that were not immediately recognized in the wake of Mr. Obama's nine-point primary loss.
"They do the registration and field stuff very, very well," he said. "Had they not done the registration and the field as well as they did, I think we would have beaten them by 17, 18, 19 points."
According to the Department of State, 218,923 new voters registered in Pennsylvania before the primary -- 152,775 Democratic and 40,195 Republican. Another 164,026 voters switched their affiliation to the Democrats, compared to just 14,887 who changed to Republican.
