This is why registering as an Independent in a closed primary state is really stupid.
One of my best pals is a libertarian, and he registered with the Libertarian Party. Only problem is, Kentucky is a closed primary state. I tried to explain to him that he should register with one of the two major parties since he could at least have a say in choosing the more "libertarian leaning" primary contestant, but he wouldn't listen. It's not like there would be anything stopping him from voting for a Libertarian candidate in a general election. Also, it's not like the Libertarian Party in Kentucky is going to have a hotly contested primary to vote in anytime soon.
