It has been a phenomenal week for Hillary Clinton's presidential bid. Clinton took a commanding lead over Barack Obama in the latest Public Policy Polling survey in Pennsylvania.

The latest poll numbers show Clinton with 56% compared to Obama's 30%.

According to the research, Clinton is doing better than ever among her key demographics such as older and female voters. Hillary is also holding Obama back in his key areas. The poll shows that Obama scored highest among black voters with 63% of those polled. While that may seem like a large number, it is much lower than other states.

The Clinton campaign plans to score big in Pennsylvania to prove to Super Delegates that she can win tradition swing states in the general election.
