There is no way in heck that the new fans that appeared because of Zenyatta will stick around in numbers great enough to positively impact the game. Did we gain a few new fans that will become regulars, most likely.
I think Zenyatta came along at the perfect time. This country needed a pick me up of sorts in the form of a positive story and someone or something to root for. I believe that's a part of why Zenyatta gained so much positive attention.
After all, we can't blame Zenyatta for voting for the wrong candidate, she clearly had nothing to do with the state of our economy, she already gets superior health care, and I don't think she has had any negative impact on the unemployment rate.
I'm looking foward to seeing her babies. Rachel's babies too. Oh $hit I just thought of something. What if their babies meet up in a race? AHHH!!! The saga will continue on.
