Not yet (probably never will).
When I was registered as a Libertarian in Los Angeles County, I kept having my name not on the list at the polls and having to do a provisional ballot. I never followed up to see if my vote actually counted, but wouldn't be surprised if they didn't since none of the votes ended up being so close that they would need to take mine into consideration. There was no apparent reason for it all, but it's very curious that when I re-registered as a Republican one election, everything went fine.
Thanks for reminding me to never register as a libertarian. Sorry you had to go through that.
