State lawmakers in Massachusetts unveiled a new draft congressional map on Monday that pits two incumbent House members against each other, but also gives one an escape hatch.

The homes of Massachusetts Reps. Bill Keating (D) and Stephen Lynch (D) are both in the newly redrawn 8th congressional district. But Keating owns a vacation home in what will be the 9th district, clearing the way for him to run there instead.

While the map made major changes, including expanding the state's only majority-minority district, there won't be the same fight over partisan balance of power seen in other states undergoing redistricting, because every member of the state's House delegation is a Democrat.

Massachusetts is losing one House seat due to slower-than-average population growth in the once-per-decade reapportionment and redistricting process that follows the U.S. Census.

That led many in the Bay State to fear that two sitting members would be forced to run for one slot. But Rep. John Olver (D-Mass.) spared his colleagues that dilemma by announcing in October that he will retire.
