The rumors swirling during August that U.S. Rep. Joe Kennedy would challenge U.S. Sen. Ed Markey in the primary have born fruit with Kennedy’s official announcement that will take place tomorrow. Kennedy, who will be 39 in October, is the son of former Democratic U.S. Rep. Joe Kennedy and the grandson of the late Robert Kennedy. He was raised in suburban Boston and earned a Bachelor’s degree from Stanford University and a law degree from Harvard where Elizabeth Warren, a woman he hopes to join in the Senate if she doesn’t make it to the White House first, was his professor. Between college and law school, Kennedy did a tour with the Peace Corps in the Dominican Republic. After law school, he was an assistant district attorney. Kennedy was elected to represent the 4th congressional district in 2012, succeeding longtime Democratic U.S. Rep. Barney Frank. The district takes in the suburbs just to the west and south of Boston. It has a Partisan Voting Index of D+9, meaning it votes nine points more Democratic than the nation as a whole.
