Why did Romney's team erase their e-mails when they left office in 2006?

Just before Mitt Romney left the Massachusetts governor’s office and first ran for president, 11 of his top aides purchased their state-issued computer hard drives, and the Romney administration’s e-mails were all wiped from a server, according to interviews and records obtained by the Globe.

Romney administration officials had the remaining computers in the governor’s office replaced just before Governor Deval Patrick’s staff showed up to take power in January 2007, according to Mark Reilly, Patrick’s chief legal counsel…

Secretary of State William F. Galvin, who oversees the state Public Records Law, said it appeared odd that state property – in this case, hard drives – was essentially being sold to private individuals.

“I don’t sell things to people who work for me,’’ said Galvin, a Democrat. “I’ve heard of people getting their chair or something as a gift. But generally if you work for me you don’t take your laptop with you when you leave.’’
