The "OMG vote like your life depends on it" crowd are all going to vote blue anyway. Their shrieking from the rafters is not going to convince undecided voters. But their ensuing "burn the fucker down" tantrums serve to move undecideds, independents and patriotic dem voters away from them in droves.

They are shouting "Trump is tearing the country apart" literally as they are tearing the country apart. Seeing is believing.
