Apparently she gained a lot of views on social media with that song. Writing some song with clever/funny lyrics doesn't necessarily make the person a talented singer. I would assume many vote for her since they liked her original song and much as I have mentioned previously, the winner might be someone with a large following for some other reason who happen to vote for them. A few years ago, a radio DJ with a big following won Dancing with the Stars even though you could see he was only a mediocre dancer.
