In terms of the Democratic LG slot, it really doesn't matter which one you vote for. Both of them are equally awful, and Bolling will walk through them like a tank through TP.
I'm in the 35th district, and the Dem you want to vote for there is Esam Omeish. This guy is on tape praising Palestinian suicide bombers for killing Israelis and advocating that muslims in Lebanon follow the "jihad way." He's a disaster of a candidate and Jim Hyland should be able to trounce him easily.
There's nothing wrong with an Operation Chaos type grassroots effort by Republicans to get out and support the weakest Democratic candidate in their primary. Until Virginia wakes up and recognizes that open primaries and conventions are a bad way of choosing candidates and we get voter party registration and closed primary elections, this is a viable tactic and one we shouldn't eschew out of some misguided notion that there is something unseemly about it.
I would suggest that those who want to do this vote for Moran. At this point, he's the weakest of the three Democrats and he is doing significant damage to himself with the Democratic base by launching a variety of poorly thought out attacks against McAuliffe. Generally, I think both Moran and McAuliffe are weak candidates, but McAuliffe is a better fundraiser, which makes him a greater threat.
The whole idea that we should choose the most conservative of the Democrats in case we lose doesn't make a lot of sense to me. Both Mark Warner and Tim Kaine were both considered to be fairly moderate for a variety of reasons, but we all know full well that neither of them were conservative on the issues that mattered. In the end, the only way we can be sure that we will have someone in office who represents our Republican principles is by electing a Republican.
You also need to remember that there is far more to being Governor than just the individual in the job. All of the various appointments made by the Governor matter too, and if Deeds wins, those will all go to Democrats, regardless of whether they are as conservative as Deeds or not. Those people will all have influence and they are likely not going to be conservatives like Deeds is.
Whatever we do, we should be focused on ensuring that McDonnell gets elected. The best way to do that is to put the weakest Dem up against him, and right now that is Moran.
