From Iron Knee at Political Irony:
People who hate all the presidential candidates, but still end up voting for one of them
Who are these people? According to one pollster, “There are a number of people who hate politics and politicians, and they play somewhat of a swing role in the country.” Let’s call this demographic the haters.
In 2016, both Donald Trump and Hillary Clinton had high disapproval ratings, and almost 20% of voters were “haters”, which makes it a rather significant demographic. In exit polls during the election, Trump got 17% more of the hater vote than Clinton. This was more than enough to change the winner in several of the battleground states.
Indeed, our Electoral College system turn a 17% lead in a single demographic group into the difference between winning and losing. This is especially true for a demographic like haters, which is spread out over a large number of states.
