Exit polls: This was a message to Trump
"Half of Virginia voters said Trump was a reason for their vote — with twice as many saying they were voting to oppose Trump (34 percent) as to support him (17 percent)."
So the Democrat started with a 17-point edge on issues that had nothing to do with any issues separating him from his opponent. Basically, he didn't need to campaign at all on Virginia-based issues.
And he probably didn't do all that well at it, since he only won by 9, despite that 17 head start. Only 99% of the voters went for one of them, with 1% going to third-party or independent candidates. We know that 51% cast a pro- or anti-Trump vote. That leaves 48% to account for, and they apparently split 28-20 for the Republican. In other words, Virginia voters are not rejecting conservative values at all, but they are directly rejecting Trump.
