Looks like there isn't going to be a 22nd debate for Clinton and Obama. Too bad, I was really looking forward to this one.

From ABC:

RALEIGH (WTVD) -- The democratic presidential debate scheduled for April 27 has been cancelled.

According to the North Carolina Democratic Party, time constraints and logistical issues associated with such a large, national event forced officials to cancel the debate.

Barack Obama had declined to commit to the event, saying he wasn't sure it would work with his schedule. The Illinois senator had previously said he would be able to debate in North Carolina, but on a date before Tuesday's Pennsylvania primary.

Hillary Rodham Clinton had agreed to the later debate, and the state's Democratic leaders had urged Obama to join her. The forum would have been the first moderated by CBS News anchor Katie Couric.

In a press release sent out, party officials also admitted to "growing concerns" about what another debate would do to party unity.

Both Senators Clinton and Obama will be visiting North Carolina again before the May 6th Primary.

In addition, Senators Clinton and Obama have committed to attending our Jefferson-Jackson Dinner on Friday, May 2 in Raleigh.

The contenders have debated 21 times during the presidential campaign, including an event last week in Pennsylvania.
