With a little less than four weeks until the next primary in Pennsylvania, the realization is setting in that we are in a phase of the Democratic race that most people will probably want to forget as soon as it is over.

With no primaries or caucuses to focus on, the press corps will take what it can get every day - and both Team Obama and Team Clinton are more than happily filling the void.

As I noted yesterday, where else can you get a back and forth over when Barack Obama says he was conceived and what inspired his parents to get down to business?

Where else can you find at least one or two high profile supporters who run their yap and go off mesage each week?  (Paging George McGovern....paging George McGovern.)

Trying to regain a bit of post-Bosnia-Sniper story momentum, the Clinton camp zapped out an email missive to reporters on Wednesday entitled, "The Obama Record, Just Words."

"We are happy to discuss Sen. Clinton's foreign policy experience and her record overall.  Unfortunately, the Obama campaign doesn't want to discuss its candidate's record and prefers personal attacks instead," said the Clinton release.

Team Obama meantime zeroed in on Clinton's discussion on Tuesday of Rev. Jeremiah Wright.  She was asked about it at an editorial board meeting with a Pittsburgh newspaper.

"It's disappointing to see Hillary Clinton's campaign sink to this low," said Obama spokesman Bill Burton.

Also in the crosshairs, the ole trip to Bosnia.

"Clinton's fantastic invention of a sniper-raked landing is only one in a growing list of instances in which she has exaggerated her role as First Lady, particularly with respect to domestic policy," the Obama release said.

Okay, I'll give Team Obama a point extra for "sniper-raked."

The Obama Camp also demanded again that Clinton publicly release her tax returns, as Obama's were made available to reporters for 2000 through 2006.

Clinton has said her tax returns should be out before the April tax deadline.

We'll give the last quote today to the Clinton campaign.

""The Obama campaign's full assault on Hillary is expanding into a full assault on the truth."

Really, when you get down to it, most of this stuff is just campaign blather.  The daily conference calls, the hit-and-run releases from both sides, the back and forth that reminds me too often of a race for 7th Grade Class President.

For this race really to be a "negative" one, we've got to have a little more excitement than this.  Still, it does move the ball down the field in terms of news coverage, and there is obviously a thirst for news on this Democratic race.

The next three-plus weeks should be very interesting.  All it takes is one really bad gaffe and the wheels start to come off.
