First, SurveyUSA shows she was leading by 19, but now she’s leading by 12.

Here are the breakdowns:

Among women, Clinton’s lead remains largely unchanged. Among voters ages 50 and older, Clinton had led by 26 points and now leads by 22. Among voters under 50, Clinton had led by 12 points but now leads by two, a 10-point swing to Obama.

In southeast Pennsylvania, which includes Philadelphia and makes up 43 percent of likely Democratic voters, the candidates have traded places: Clinton had been up two points but is now down three. In southwest Pennsylvania, which includes Pittsburgh, Clinton had led by 31, but now is at 17, a 14-point swing to Obama. […] In the northeastern part of the state, which includes Scranton, there is movement to Clinton.

The survey concluded that there is also movement to Obama from conservative and anti-abortion Democrats.

What’s more, Rasmussen has Obama within 5% of Hillary in PA

The latest Rasmussen Reports telephone survey in Pennsylvania shows Clinton leading Barack Obama by just five percentage points, 47% to 42%. For Clinton, that five-point edge is down from a ten-point lead a week ago, a thirteen-point lead in mid-March and a fifteen-point advantage in early March.

Support for Clinton slipped from 52% early in March, to 51% in mid-month, 49% a week ago, and 47% today. During that same time frame, support for Obama has increased from 37% to 42%.

Obama recently received a key endorsement from Pennsylvania Senator Bob Casey and has also spent more on television ads than Clinton. If Obama is able to pull off an upset in the Keystone State, it would effectively end the race for the Democratic Presidential Nomination. Obama currently leads Clinton nationally in the Rasmussen Reports daily Presidential Tracking Poll.

What these two polls show us is that Obama made up 7 points in the SurveyUSA poll and 5 in the Rasmussen, so it’s a safe bet that he’s closing the gap.
