DEMS STAY PUT. With the logistical nightmare posed by holding the Democratic National Convention at the FleetCenter becoming more and more apparent, Governor Mitt Romney has lent his voice to those saying that the gathering should be moving to the new convention center in South Boston. (Globe coverage here; Herald coverage here.)

Given that it's almost certainly too late to make such a dramatic shift, it's worth reminding everyone that the idea was publicly floated for the first time last December 19, in Cosmo Macero's Herald column.

Macero's money graf:

"If we got the call from the mayor or the committee ... I believe we could do it," says Jim Rooney, chief executive of the Massachusetts Convention Center Authority and Menino's one-time chief of staff. "It would look different. But it could and would be made to look like a good media event, which is by and large what conventions are."

The traffic and security concerns would be so much more easily solved at the desolate South Boston location than at the FleetCenter, which is the hub of the Greater Boston's public-transportation network as well as the nexus of the city's highway system.

But, of course, the move isn't going to happen. All we can do is hope for the best.
