FILE - In this July 14, 2006, file photo, Massachusetts Gov. Mitt Romney uses a map of the Big Dig tunnels to make a point about potential trouble spots during an afternoon briefing in Boston. Romney was at his New Hampshire vacation home on a summer night in 2006 when tons of concrete ceiling panels in one of Boston’s Big Dig highway tunnels collapsed. The debris crushed a car and killed a female passenger. Romney, then in his final year as Massachusetts governor, dashed back to Boston and immersed himself in the crisis. His response offers insights into what kind of leader the expected Republican nominee would be if elected president. Romney has made his management skills a major selling point in his campaign.
