MEDIA, Pa. -- Sen. Hillary Rodham Clinton has what it takes to improve education, provide more access to health care and increase funding for clean energy projects, Bill Clinton told a crowd of more than 1,000 at Pennsylvania State University's Brandywine campus yesterday.

Mr. Clinton said his wife is a "change-maker" who has a plan to reduce the national debt, create jobs and improve the economy.

The former president is the second Clinton to visit Pennsylvania since the New York senator's three-state primary win Tuesday turned the state into a political battleground.

Daughter Chelsea was in Philadelphia Wednesday, and Mrs. Clinton is expected in Scranton Monday to kick off six weeks of campaigning.

Meanwhile, she was in Mississippi yesterday, and Miss Clinton was campaigning for her mother in Wyoming, which holds its caucuses today. Missississippi's primary is Tuesday. After that, all efforts of both Democratic candidates are expected to be focused on Pennsylvania until the April 22 primary.

At stake is a mother lode of 158 primary delegates, the most of any state that hasn't yet held its primary. Another 30 -- the state's most dominant Democrats -- are superdelegates, who are not obligated to vote in accordance with primary results.

Earlier in the day Mr. Clinton met with Philadelphia Democratic ward leaders, who also heard from U.S. Rep. Patrick Murphy, D-Bucks, representing Sen. Barack Obama, of Illinois. Ward leaders told the Associated Press they will wait to endorse until they have heard from both candidates in person.

Meanwhile, at the rally, Mr. Clinton's goal was to woo the crowd with policy details, not a lot of "whoop-dee-doo."

He explained the steps his wife would take as president: She would divert special-interest tax credits to clean-energy projects. She would promote the manufacture of fuel-efficient cars. She would work to increase teacher salaries and reduce standardized testing.

Mr. Clinton mentioned Mr. Obama, her primary opponent, only once during his 45-minute talk, mentioning "some heated exchanges" between the candidates about health care policy.

"Her plan would cover everybody, and he says that's coercive. But his plan would leave 15 million or 20 million people out," Mr. Clinton said. "You can't control the cost of health care unless you cover everyone."

Yesterday's talk drew a crowd of 1,500. Elizabeth Swift, who arrived at 9:45 a.m. for the 2:30 p.m. speech, was first in line and scored a spot in the standing-room-only crowd just a few yards from Mr. Clinton's podium.

Miss Swift, 22, who traveled from northern Delaware -- only a few miles from the campus -- hasn't been politically active before, and only registered to vote a month ago, too late to have a say in her state's primary. She said the quality of both Democratic candidates inspired her to take an interest now, but make no mistake: She plans to vote for Mrs. Clinton.

"Barack Obama is a good guy. He could get the job done. I just like Hillary more," she said.

Others in the crowd, such as Mark and Samantha Savukinas, of suburban Philadelphia, who attended with their 3-year-old daughter, are undecided. Democrats both, they plan to attend any Philadelphia-area events planned for Mr. Obama and Republican Sen. John McCain, too, because they want to be informed voters.

"We're excited that Pennsylvania makes a difference now, so they're all going to come here," Mrs. Savukinas said.

Yesterday's rally wasn't unusual, said Mr. Savukinas, who has attended numerous political events over the years.

"This wasn't a 'rah-rah' event. He was here to say, 'This is what my wife is going to do,' and that's what people wanted to hear," he said.

Mr. Clinton noted that, too.

"Listen how quiet it is here," he said to the crowd. "This isn't a traditional rally. You've let me explain the intricacies of energy policy and education policy. Why did you do that? Because you know this is an important election. You know we have to turn this country around."
