LEWISBURG — Democratic presidential candidates Barack Obama and Hillary Clinton are down to the wire in their race to win — or in Obama’s case, not lose big in — the Pennsylvania primary.

With a week and a day left before voters head to the polls, Mrs. Clinton has dispatched her staunchest and, arguably, most popular supporter: her husband.

Former President Bill Clinton appeared before a mostly-full Sojka Pavilion at Bucknell University Sunday morning to make the case for why his wife is the best choice among the three remaining presidential candidates.

“I’m telling you, I’d be here for her even if I didn’t marry her,” he said, “because I think she’s the best changemaker.”

During a recent campaign stop, his daughter, Chelsea Clinton, was asked whether she thought her mother would make a better president than her father. The former first daughter responded by saying she did.

“And I agree,” Mr. Clinton said Sunday, “because (Hillary’s) better prepared for it.”

During his hour-long speech, he touched on his wife’s plan to reinvigorate the sagging economy with a focus on energy independence.

Energy, he said, “is the only thing that has generated jobs across the world in every area ... America has not even scratched the surface of what it can do with solar energy, wind energy, biomass fuel.”

He also explained Mrs. Clinton’s plans for education (“a radical rewrite of No Child Left Behind”), withdrawing troops from Iraq and taking care of wounded veterans.

Speaking about health care, he said, “I want to talk about this, even though most of the people in this audience are young and probably aren’t that worried about it.”

The crowd was a mix of young and old however, with Bucknell’s trademark bright orange making it easy to spot the students.

Several students said they were still on the fence between Mrs. Clinton and Obama and didn’t know enough about the issues to make a decision yet.

“I’m interested to see what (Mr. Clinton) has to say today,” said 19-year-old Jessica Horne, a sophomore. “Looking at a lot of their issues, they seem really similar.”

Her friend, sophomore Jackie Denning, said, “I like both candidates, but Hillary seems to have more of a plan. But I like Barack’s ideas.”

Ashley Roselle, a 22-year-old junior, said Barack Obama has a large, vocal and, in her opinion, obnoxious contingent on campus.
