How will the "anti-tax, anti-abortion, pro-gun candidates" fare in this week's primaries?

This article in the Richmond paper says that "Virginians will find out Tuesday how far to the right Republican voters are willing to go." Likewise, this AP report surveys the scene from the weekend before the primaries, which also notes that "[t]he challengers are bound by unconditional resolve to block any type of tax increase and cut taxes if possible. They also want abortion outlawed and oppose restrictions to owning and carrying firearms."
