Curious Omission

There's been a good amount of commentary recently about the Republican Party of Virginia's controversial decision to institute a "loyalty oath" for voters in the 2008 Republican Presidential Primary, which the RPV subsequently overturned (to near-universal praise, as in this editorial in yesterday's Daily Progress). It's curious to me that there's been no mention (best I can tell) of the fact that the Charlottesville Democratic Party has for years required the very same kind of oath by participants in its nominating caucus. I've never liked it, frankly, for many of the same reasons that have been mentioned in opposition to the Republican Party's short-lived loyalty oath. Is it time for our oath to go too?
