Survey says: Like Hell!

If predestination is caused/enforced by a higher power, then the existence/non-existence of free will should be observed from the viewpoint of that higher power, in which case it becomes obvious that we have no free will.

Assuming, of course, that you believe in predestination in the above form. I don't. If there is a sort of predestination, I prefer to think of it in terms of prediction, like looking at a basketball mid-air and calling whether or not it's going in the basket. With that paradigm, we get predestination AND free will, best of both worlds. :-)
