Joseph Kennedy III has moved to a different Boston suburb ahead of an expected congressional bid to replace retiring U.S. Rep. Barney Frank.

Brookline’s town clerk says the 31-year-old Kennedy came to town hall Tuesday and registered to vote as a Democrat, listing a Brookline address. He’d been living in Cambridge, which is in a different district.

Kennedy is the son of former U.S. Rep. Joseph Kennedy II and a grandson of the late Robert F. Kennedy. The family has deep ties to the Boston suburb.

Kennedy announced last month he was forming an exploratory committee to look at a possible run for the seat.

A spokesman says Kennedy is taking time to listen to families in the district.
At least two other Democrats and two Republicans are considering runs.
