Gov. Patrick, Sen. Kerry to Speak at DNC

Joins Rahm Emanuel and others.

Gov. Deval Patrick and U.S. Sen. John Kerry have been tapped to speak at next month's Democratic National Convention, the party announced Monday, setting up what appeared to be a key role for Massachusetts Democrats as the party geared up for the fall presidential campaign against former Republican Gov. Mitt Romney.

Patrick, who was Romney's successor, will address the delegates on Sept. 4, the second night of the four-day gathering in Charlotte, N.C.
