Following a meeting held yesterday with Senators Tom Harkin, Jon Tester, Tom Carper and Ken Salazar, the Rocky Mountain News reports that Sen. Ben Cardin (D-Baltimore) is set to attend another, larger gathering of the Senate's undeclared Democratic superdelegates.

The meeting will not take place until Wednesday, implying that Cardin's endorsement will likely not come tonight. Yet Harkin, who allegedly brought the group together, told the paper that he is unsure whether the group will end up voting as a block.

This all may change, as an AP newsflash reports that Hillary Clinton campaign officials say the Senator will acknowledge that Sen. Barack Obama has enough delegates for the nomination during her New York speech tonight.
