For Edwin David, who served with the famed World War II unit of black fighters known as the Tuskegee Airmen, Sen. Barack Obama is an easy choice.
"Just let me live till voting time in November," said David, 83, living in retirement in the Pocono Mountains. "In my lifetime, we just might get to see the first African-American president of the United States!"
Fresh from victories in the big states of Ohio and Texas, and with polls having shown her holding the lead here, even if it has dwindled, Sen. Hillary Rodham Clinton starts her campaign in Pennsylvania as the favorite to win the April 22 primary.
But in random interviews last week with dozens of voters in swing districts across the state, much of the Democratic voter enthusiasm seemed to tilt toward Obama, not only because he is a fresh face, but because they believe he has the best shot at beating Republican nominee-in-waiting John McCain, whom they call old and out-of-touch.
But unlike David, many said it wasn't an easy decision.
Kate Clark, 53, a cafe owner in Nazareth, a small town near Allentown, said she struggled with her choice. Tempted to vote for Clinton because of her gender, she said Obama's energy and vision ultimately won out.
"I think we need to see the United States and see the world through eyes that are younger, through eyes that have dreams, through eyes that see something new for the nation," Clark said.
