What are the consequences of Obama's Campaign letting Clinton's name be put in for the nomination?

John Fund has this discussion today at the WSJ's Political Diary:

The Obama campaign was in full spin mode yesterday touting its decision to allow Hillary Clinton to have a roll call vote at the convention so her delegates can register their support of her.

"It's an olive branch that we think will pay dividends in party unity," one Democratic congressman told me. I'm not so sure. Many Clinton supporters will be appreciative of the symbolic gesture, but others such as those who unofficially call themselves Pumas (Party Unity My Ass) may see it as an opportunity to make more trouble for Mr. Obama both on and off the convention floor.

"The one thing that Obama should never have agreed to is a roll-call vote with Hillary Clinton," says Jeff Birnbaum, a Washington Post columnist. Mr. Birnbaum nonetheless admits to being "so grateful that we are going to have a story, which is Hillary Clinton's attempt tacitly to take over the Obama victory, and that [story] will go through virtually every day of the convention" given how frequently Bill and Hillary Clinton are scheduled to appear before delegates.

Indeed, the Clinton people I spoke with appear emboldened by the Obama concessions. . . .
