One month after the Maryland primary, Montgomery County Councilman Marc B. Elrich (D) was finally able to celebrate his victory in the Democratic primary for county executive, with a party Thursday night at McGinty’s Public House in downtown Silver Spring.Which means that attorney and lobbyist Leonard N. Lucchi can start celebrating, too.Len LucchiNow that the Montgomery County race is officially over, so is the Maryland Matters primary prediction contest. And Lucchi, who already demonstrated his superior knowledge of Maryland politics by being on the winning team of our trivia contest earlier this year, has won this one as well.The fix is not in! Lucchi simply knows a ton.So Congratulations, Len! Maryland Matters Editor Josh Kurtz will be treating you to lunch soon.We had four dozen entries in this contest. And we needed the tie-breaker for Lucchi to defeat Mary Clapsaddle, Johns Hopkins University’s director of state affairs. Lucchi predicted three of the four winners of the Montgomery County Council at-large Democratic primary correctly; Clapsaddle called just one of them correctly. That was the difference.If businessman David T. Blair had won the Democratic primary for Montgomery County executive — and he came just 77 votes short — then Henry Callegary, a judicial law clerk and president of the Baltimore County Young Democrats, would have been the contest winner. And Kyle Gilbert, director of operations for Gov. Lawrence J. Hogan Jr. (R), would have been the runner-up.That’s how intense the competition was.We thank everyone who entered. And hope even more people will enter when we do a general election contest in the fall.
