Scratch one political-party primary.

Alexandria School Board member Karen Graf has rescinded her plan to challenge Del. Mark Levine (D-45th) in the June Democratic primary. Her decision likely leaves Levine and the three other members of Arlington’s House of Delegates delegation with smooth sailing to Election Day.

Graf, who earlier announced plans to take on first-termer Levine, pulled out without a great deal of specificity as to why. Her decision came before she had a chance to unveil her candidacy before the Arlington County Democratic Committee, which serves as the unofficial launching pad for Democratic candidates.

The 45th District includes just a handful of precincts in Arlington, mostly in the Shirlington/Fairlington area. The district as currently configured is centered in Alexandria.

Prospective candidates have until the end of March to file to run in June’s primary. But with Graf’s pullout, it appears that Levine and Dels. Patrick Hope (D-47th), Alfonso Lopez (D-49th) and Rip Sullivan (D-48th) will have no intra-party challengers.

To date, only Lopez has picked up a general-election challenge, with Republican Adam Roosevelt seeking to unseat him. The 49th District is heavily Democratic, suggesting Lopez is unlikely to have a difficult time retaining his post.
