The polls were (and still are!) virtually silent after the GOP Convo, largely because they were waiting for a bounce that never came. I suspect we'll see more silent pollsters over the next 3-6 days, but for the opposite reason: they try desperately to spin or diminish the obvious bounce for the President.
