Obama Sharpens His Knives

Barack Obama is planning on getting tough. Finally.

Senator Barack Obama will intensify his assault against Senator John McCain, with new television advertisements and more forceful attacks by the candidate and surrogates beginning Friday morning, as he confronts an invigorated Republican presidential ticket and increasing nervousness in the Democratic ranks.

Senator Barack Obama greeted Senator John McCain at a forum on public service Thursday night. Mr. Obama planned to begin intensifying his assault against Mr. McCain on Friday.

Mr. McCain’s choice of Gov. Sarah Palin of Alaska as his running mate and the resulting jolt of energy among Republican voters appear to have caught Mr. Obama and his advisers by surprise and added to concern among some Democrats that the Obama campaign was not pushing back hard enough against Republican attacks in a critical phase of the race.

Some Democrats said Mr. Obama needed to move to seize control of the campaign and to block Mr. McCain from snatching away from him the message that he was the best hope to bring change to Washington.

After back-to-back attack ads by Mr. McCain, including one that misleadingly accused Mr. Obama of endorsing sex education for kindergarten students, the Obama campaign is planning to sharpen attacks on Mr. McCain and Ms. Palin in an effort to counter Mr. McCain’s attempt to present himself as the candidate of change with his choice of Ms. Palin.

Here we go.
