Clinton's Final Pennsylvania Push

WEST LAWN, PA -- In the final days before the Pennsylvania primary, Hillary Clinton's campaign has acquired... well, what you might call a fierce urgency of the now.

"There is plenty of work to do," but "I have to win, and that really depends upon what happens on Tuesday in the Pennsylvania primary."

At a high school here, she led the crowd, mostly students and in their parents, in a chorus of "Yes we can!"s.

Earlier, at a volunteer fire house in West Chester, Clinton urged the crowd to consider the consequences of falling for what she called "whoop-dee-do speeches" which, she said, gets "everybody whipped up." Instead, ``I want everyone thinking.'' The job of president, she said, requires serious attention. "The pressures of the job are enormous." (I took that as a jab at Barack Obama.)

Clinton predicted a record turnout on Tuesday. "I can win only with your help."

Briefing reporters on the brand new campaign bus, Pennsylvania state director Nick Clemons four times brought up Obama's financial advantage over Clinton, asserting that the "race will be close" despite polling showing a healthy Clinton lead.

Clinton's campaign has 5,000 full-time volunteers who will make 500,000 house calls this weekend and help to place a million phone calls. The complex distribution of delegates is playing some role in determining where Clinton campaigns. "We are aware of the delegate math," Clemons said.

As we left the high school en route to our third event, Clinton press aides e-mailed reporters the latest result from Gallup's rolling tracking poll of Democrats and voters who lean Democratic. A lead outside the margin of error for Obama has shrunk to a tie.

A note on crowds: Clinton is attracting about 1,000 people per event. Last night's mega-rally aside, Barack Obama's crowds in Pennsylvania are usually the same size.
