I believe the group of low information voters is a lot larger than some people here think. We get caught up in our bubbles. It's like me thinking that everyone is over using batting average and pitcher wins to evaluate players because almost all the people who I talk to online have gone beyond that (unintended sales pitch!). Then I talk to casual and not so casual fans in real life who are still stuck on batting average and wins.
Professionally, I am surrounded by people who are more savvy than me politically (either that or unrealistically far left), but the majority of family and friends either don't give a crap or have no idea how bad Trump is. There are a lot of people out there who know he's stupid and nasty, but "he's a businessman who knows to get things done" or he is "stupid , but he's tough so nobody will mess with him".
