Democrats are still waiting for a decision in their lawsuit seeking a new election in the Stafford-area 28th District, which was won by Republican Bob Thomas by 82 votes.
The most recent one-vote margin in a House race was in 1991.
The caucus vote comes after a day after Democrats appear to have secured a 50-50 tie in the lower chamber with a one-vote election victory after a recount in a Newport News House district.
And it leaves the balance of power in the state legislature at 49-51, in favor of Republicans - at least for now.

The entire scape of the Virginia state legislature was changed Tuesday after a recount finalized a Democrat's victory in a seat formerly held by a Republican with a margin of just one vote.
According to the Richmond Times-Dispatch, the ballot in question was "bubbled in" for both Simonds and Yancey but also crossed out through Simonds' bubble.

The two were battling for the 94th District in Newport News.
Democrat Shelly Simonds emerged from the recount as the victor of the 94 District of the House of Delegates, defeating Republican incumbent David Yancey, The Washington Post reports.
A fourth recount in the Fairfax County-centered 40th District confirmed the victor as incumbent Del. However, the bubble for Gillespie had an X mark and the bubble for Simonds had a slash-like mark.
The statement continued, "The State Board of Elections will publicly meet to make a determination by drawing lots, after which the loser may request an additional recount".
The judges are meeting to certify Tuesday's recount.
