Anybody up for a new president?

Here’s a snapshot of where the Democratic race for president is right now, in the final few days before what could be a decisive primary election on Tuesday.

“Now it is our turn, Pennsylvania,” said Mr. Obama, speaking at his first stop in the Philadelphia suburb of Wynnewood. “This is a defining moment in our history. All of you are here because you can feel it.”

If Mr. Obama’s final Saturday before the Democratic primary in Pennsylvania appeared bucolic, as he rumbled from Philadelphia through the lush green Amish farming country, Mrs. Clinton, by contrast, lived up to her workhorse reputation with a day that required driving and flying long distances to her five events. Mr. Obama drew sharp distinctions with Mrs. Clinton, hoping to narrow her advantage, while she barely referred to him in her remarks to voters.

This race has grown decidedly meaner and uglier in the past week.

Mrs. Clinton stayed close to her usual pitch, pressing on the issues of education, the war in Iraq and the economy, and she led the crowd in a chant of “Yes, we will,” her variation of Mr. Obama’s mantra of “Yes we can.”

The two campaigns sparred over their respective health care plans, with Mr. Obama putting forth a television commercial that attacked Mrs. Clinton’s proposal. She returned the criticism, saying, “He chooses to attack my solution.”

This is a no-win situation at the moment.

And the candidate of change didn’t have this in mind.
