If Trump wins and liberals are definitely going to lose their mind, this might  be the moment they revolt against the democratic establishment for lying to them. They will wake up every morning seeing Trump tweets and remember that CNN told them for a year that it's all fine and all good and now they're about to lose "democracy".

Republicans should mention this every chance they get to make it look that all liberals nightmares are happening because the democratic establishment lied to them.

No they won't! The Dems were told that Hillary would win in 2016. They were not only told they were reassured.  I watch CNN all day and popped on 538 once a day during 2016. Nobody will be surprised by either choice they both are equally unfit.
