Senator Clinton has not taken a position on whether she will concede the nomination prior to the Convention. Nor, in my opinion should she. She has not been pushed around with regard to how to run her campaign so far, why start now. The Rules Committee is busy dealing with Michigan and Florida; the superdelegates may take positions now that change in a week or a day; and if we want a Democrat in the White House this January we all better hope that Senator Clinton remains open to becoming the nominee.
