It's probably safe to say the donations will be similar in proportion to November 5th. So... there'll be a "spike" at 12 am before it calms down for the night, but later in the day money will be rolling in constantly much faster than it will in the first hour.
It is the middle of the night, after all. The people that have seen this poll and would respond to it the fastest are going to be the ones most on top of things and probably the ones most likely to be donating first thing, as well.
