> Remember last US pres election polls by CNN? Completely wrong.

I do. I don't remember that at all. I think you might have some odd definition of completely wrong though.

But please, by all means, share these 100% wrong polls that showed, for example, Trump having 0% chance of winning. Most of the polls I saw were fairly accurate within their margin of error and made it clear the race was tight (which, in the end, it was). And nothing I've seen has changed that, but if you have polls from CNN specifically that you can point to, by all means.
