Atiya Abdelmalik voted for change Tuesday.

The Leetsdale resident was one of nearly 2.3 million registered Democrats in Pennsylvania expected to cast a vote for either Sen. Hillary Clinton or Sen. Barack Obama.

"I'm here because I want to see change happen and I believe it can," she said while leaving Quaker Valley High School, the site of Leetsdale's polling place.

"The only way for us to show that we can make a difference is for us to come out and vote for those candidates that represent what we want to see changed.

"Change can't occur if you don't take action."

Clinton won the Keystone state with a decisive lead, picking up at least 66 delegates to the party's national convention, with 35 still to be awarded, according to unofficial results.

Six weeks after Clinton and Obama began stumping across the state, voters had their turn to react.

By 6 p.m. on Tuesday, 252 Leetsdale Demo-crats kept Merna Poninsky and other poll workers busy since polls had opened 11 hours earlier. The group recorded 68 Republican votes by that same time.

Turnout in Leetsdale was high, said Poninsky, who woke up bright and early at 4:30 to prepare for the larger crowds.

"It's been good," she said. "We've had a lot of new faces showing up here to vote -- young people."

Leetsdale's increase mirrored that of polling places across Pennsylvania as voters under 30 were expected to turn out in droves.

Not every polling location had a high turnout, though. In Osborne, poll workers recorded 76 Democrats and 45 Republicans by 6 p.m. with the bulk of voters casting ballots around lunch.

Across the state, 2.3 million of Pennsylvania's 4.2 million registered Democrats were expected to flock to the polls, according to the state's election office.

A record number of 8,328,123 Pennsylvanians were eligible to vote on Tuesday including 152,700 newly-registered Democrats and 40,000 new Republicans since Jan. 1.

But at least one Pennsyl-vania resident wasn't able to vote in Tuesday's history-making primary.

Having relocated to Leets-dale several months ago, Ohio native Scott Nelson, 23, hadn't registered to vote in Pennsyl-vania before the primary cut-off last month.

His reasons for wanting to vote are similar to others.

"Being fresh out of school and being in the working world, you really get a sense of how important the economy is," Nelson said.

Social security and universal health care also factor into Nelson's support of a candidate.

As candidates begin to recognize the importance of the so-called "youth vote," Nelson said more college students will begin to take note of issues that are important to them, forcing candidates to take notice.

"As more and more college students enter the workforce, they realize how things like health care and social security affect them," he said.

"Our vote is important."

Tuesday's election leaves nine states left in the Democratic race for the White House. The convention will be held in August.

Pennsylvania's 158 delegates were the largest left up for grabs across the nation.

The state has a total of 28 superdelegates.
