BOSTON -- Earlier this week, Gov. Mitt Romney suggested it may be better to hold this summer's Democratic National Convention at the new convention center in South Boston.

Janet Wu Reports On Location Debate

NewsCenter 5's Janet Wu reported that the Massachusetts Congressional Delegation lashed out at Romney Friday, warning he'll be the "skunk at the lawn party" if he continues down this path.

At a party fund-raiser Friday, Democratic congressional campaign committee chairwoman Nancy Pelosi led the party's Massachusetts bigwigs in questioning Romney's motives in suggesting their party be moved from the Fleet Center to the yet-to-be-opened convention center.

"One would have to wonder why a governor would try to disrupt the planning of the convention that is imminent. It either shows a lack of understanding of the kind of planning it takes to put on a convention or some mischief," said Pelosi.

"This is John Kerry's hometown, and the Republican Party is going to absolutely be obsessed with making John Kerry's life uncomfortable," said Rep. Edward Markey.

Mayor Thomas Menino calls it political mischief.

"Up until a month ago, they were as cooperative as I could expect, and the change in attitude recently, someone is giving him bad advice and that is unfortunate," said Menino.

Menino said commitments to move the elevated Green Line are suddenly gone, buses to move conventioneers are uncertain, and Massachusetts Turnpike land to park media trucks may not materialize.

The governor refused comment on the issue Friday, but earlier this week, he was blunt.

"I would note it will be disruptive to traffic," Romney said Tuesday.

"I don't think he wants to be responsible and be the skunk at the lawn party. I would hope that the governor would put aside the politics, the pettiness," said Rep. William Delahunt.

A representative for the governor insists Romney never spoke with the Bush-Cheney campaign about any of this. But one thing is certain: If things go wrong this July, the governor is on the record as saying he warned the Democrats -- opening the door for Democrats to accuse Romney of politically sabotaging their event.
