Last night, with 158 delegates at stake, Hillary Clinton managed to trim the deficit between she and Sen. Barack Obama by controlling the key Pennsylvania primaries.

With 99 percent of precincts reporting as of this afternoon, Clinton controlled 81 delegates to Obama's 69.

A must win state for Clinton, who trails Obama in primaries won, overall delegate count and the popular vote, the former first lady made it clear that she believes the "tide is turning."

"I won that double-digit victory that everybody on TV said I had to win, and the voters of Pennsylvania clearly made their views known, that they think I would be the best president and the better candidate to go against Senator McCain," Clinton said, in reference to the Republican nominee.

Though she still trails Obama in the delegate count by an estimated 1,719 to 1,586, Clinton made note of her recent victories in key, delegate rich states while making appearances on CNN earlier this morning.

"I won the states that we have to win - Ohio, now Pennsylvania."           Hillary Clinton"I won the states that we have to win - Ohio, now Pennsylvania," Clinton stated. "It's very hard to imagine a Democrat getting to the White House without winning those states."

According to CNN exit polls, Pennsylvania played out much like Tennessee, where Sen. Obama took the majority of the vote in all 18 to 39 age demographics, while Hillary Clinton held the edge in all demographics 40 and older.

This trend reflects what has been readily apparent at the University of Tennessee throughout the campaigning season. While Clinton took home the Volunteer state, UT students leaned largely toward the senator from Illinois, with 79 percent of students polled choosing Obama as their preferred Democratic candidate.

Though the Obama campaign suffered a key loss in Pennsylvania, they don't feel that anything will change in the Illinois senator's quest for the presidency.

"We don't believe that the structure of the race is going to change," Obama campaign manager, David Plouffe stated.

With Pennsylvania now in the rearview mirror, both campaigns look forward to the North Carolina and Indiana primaries set for May 6.
