DOVER, Del. — Republican state Rep. Joe Miro has added himself to the list of Delaware lawmakers opting not to seek re-election this year.

The 71-year-old lawmaker announced his retirement on the House floor Thursday, saying that, after 20 years, it’s time for someone else to represent his Newark-area district.

Miro, a native of Cuba, is a retired teacher and former member of New Castle County Council.

Miro is one of eight incumbents in the 62-member General Assembly who have announced that they will not seek re-election in November. The list consists of three House Democrats, two Senate Democrats, two House Republicans and one GOP senator, including the Senate’s Democratic majority leader and GOP minority leader.

Democrats currently hold a 25-16 advantage in the House and an 11-10 margin in the Senate.
