I agree, it may not be that they chose the wrong person to interview, but that they just chose the first one they could find which happened to not really be a good representation of TS voting problems as she clearly wasn't all that motivated to vote in the first place.
In light of that, my time voting this year (for the first time as myself) went smooth as could be, but the registering was the problem. I registered before the last election in 2004, which was the first election I could vote in, and had registered as <male name>. This time, I figured the easiest thing to do was to just re-register with my new name and just never deal with my old registration so I wouldn't have to out myself. That turned out to be a problem since apparently when entering in the information, the computer brought up my old information since most of the information was the same. They tried verifying using my SSN, which brought up <male name>, then they tried verifying by using my drivers license number, which brought up Sarah. This thoroughly confused them and they didn't know how to refer to me. Since everything was previously in the system as <male name> they ended up contacting me and referring to me as <male name> until I finally broke it down for them and outed myself. Luckily, the woman who was handling my registration was very nice and professional about it just said ok and updated the information to my new name. Now that my information is updated I will always be registered as Sarah and [hopefully] won't have to deal with any more voting problems again.
