The Washington Post poll concerning the Virginia gubernatorial race can be seen here. The poll does not mention the Libertarian Party nominee, Rob Sarvis, who is expected to qualify for the ballot soon. However, the poll does ask the hypothetical question of who respondents would vote for if Lieutenant Governor Bill Bolling were running as an independent (he considered doing that, but is not doing that). Those results show Bolling at 15% if he were running.
The poll also asks respondents if they are satisfied with a field that only includes Ken Cuccinelli, the Republican nominee, and Terry McAuliffe, the Democratic nominee. 45% said they were satisfied with that field, but 40% said they wish someone else were running. Thanks to PoliticalWire for the link to the poll.
