Blue-State Gerrymandering: Good for Libertarians?

In both my Congressional and State Assembly districts, there were exactly two names on the ballot—the incumbent Democrat … and a Libertarian. I'm sure someone's done the math on it, but it strikes me that there's probably a built-in percentage that any number-two candidate can expect on a two-name ballot (10? 15?). Especially considering that there are, you know, some non-Democrats living in Los Angeles. Maybe the eventual knock-on benefit of having absurdly gerrymandered voting districts areas is that third parties will contest what major parties can't be bothered with. And some day, somewhere, some might win.

In my case at least, it made an easy vote already easier: Not only is Congresswoman Diane Watson an unspectacular, overwhelming favorite running against a small-government opponent, but her office has been sending me faxed press releases for nearly four years now and they don't know how to take me off their list. Seriously. I've called them three dozen times, and they're really apologetic, but still my toner cartridge gets hosed every few months from the nonstop statements against the war & photographs with dignitaries. I might run against her myself next time.
