Yes technically they can short the entire float. But they eventually have to cover forcing the stock back up. I would think a hedge fund or funds would push this back up to take advantage of the huge short position someone has, it's probably the Seeking Alpha boys who are short. It's easy money on the long side for hedge funds as they will force the shorts to cover and thereby make fast money.
Don't let the shorts shake you out. The dust will settle and this will ride back up quickly. They can only short so much, like the entire float of 15 million. Once the big boys find out that shorts are in deep they will springboard this back up so fast your head will spin. Just hold and come back next week.
