We don't vote for the show, the characters, the writers, the production, etc. We solely vote for the acting brilliance of the actors and it would be a crime not to vote for the leads of the show as they so wonderfully show us their acting prowess, despite the show being shitty. If that doesn't deserve our votes, idk what will.
On them giving interviews and selfies, it's their own personal preference. These awards are based on their acting ability, not their rapport or if they give selfies off screen. It can't be judged like that. Anita posts 1000 selfies a day, doesn't mean we should only vote for her, right? It's not selfies, it;s acting ability.
Vote if you want to based on acting, otherwise don't. Your choice.
