RICHMOND — A race that would tip control of Virginia’s House of Delegates, whose constant and nearly comic pendulums between candidates has attracted national attention, took one more twist on Tuesday when a drawing to break a tie was unexpectedly postponed.

The Virginia State Board of Elections announced it would delay a drawing of lots after receiving a letter from lawyers for the Democratic candidate, Shelly Simonds, that she was legally fighting the ruling of a recount court last week.

The election board’s one-line announcement, on Twitter, came just hours after an announcement that there would be a live video stream of the drawing, which was to be held adjacent to the State Capitol, in response to the huge interest in the race beyond Virginia.

Republicans, who have held majorities for 17 years in the State House, cling to a 51-49 edge after a Democratic wave in elections last month. A Simonds victory would force a bipartisan power sharing and give Ralph Northam, the Democratic governor-elect, an improved shot at enacting liberal priorities.
