I'm with Gunlord here. I couldn't care less about a candidate's hobbies, but I really would have preferred a politician who does more useful things with his/her free time other than play MMORPGs or watch cinema or whatever.
God knows I love movies, books and video games but I don't have time for them when I study, even more so if I join a political movement and would have to dedicate the rest of my time to social activities.
Then, if they are digging that stuff up from her past (in before she went into politics) to hurt her, now that's dirty politics. Using a person's past habits against him is a nasty, though acceptable tool in political propaganda.
