Candidates for nearly half the seats in the 200-member Massachusetts Legislature are facing no opposition in this year's elections.

In the Senate, 20 incumbent lawmakers, the vast majority of them Democrats, face no challengers in both the primary and general elections.

In the House, more than 70 candidates, most of them incumbent Democrats, are also facing no opposition in the primary or general elections according to the state secretary's office.

Many more incumbents in both chambers face no challengers in the Democratic and Republican primaries in September, giving them a clear path to the November elections.

Democrats already hold overwhelming majorities in the House and Senate. Republicans have been trying to chip away at those totals.

Eight of the state's 11 district attorneys are also facing no competition at the ballot box this year.
