Of the 100 seats in the Virginia House of Delegates, only ten have competitive primaries. Of the 40 seats in the Virginia Senate, only 8 have competitive primaries. Only 10% of the House seats and 20% of Senate seats are up for grabs in actual primaries and in none of these 18 seats are there competitive primaries for both parties in the same district. In the general election contests right now only 26/100 and 14/40 are contested between a Republican and a Democrat. Roughly 13% of Virginia's General Assembly are giving voters a choice in its primary and only just under 30% of all 140 seats will be competed for on election day in November between a Democrat and a Republican.
But hey, it's super important to make sure incumbents can rig the system for themselves (Hanger) or their chosen replacements (McWaters, Smith). I can't even speak to the Democrats side. For the Republican side, it just speaks to the power of incumbency to scare/intimidate competition in the free market of ideas. We seem to spout free enterprise and competition in everything but our elections and primary contents. All you can do is laugh to keep from crying. I could probably think of reasons why this is (gerrymandering, incumbent protection laws, lobbyist gifts, weak state parties) what really what's the point? It's more shameful just to look at the numbers.
