If most of the people you talk to are college educated people who live in a city than you most definitely exist in a bubble. Remember 47% of the country voted for Trump(I doubt Hacker news came anywhere near this number). Of your friends how many voted for Trump? As an example I'm a college graduate in his 30's who lives in the city. 0% of the 20 people I talk to most often voted for Trump, and maybe 4% of the the extended 200 people I know, voted for trump. And of that 4%, 3/4ths voted for him begrudgingly. And I live in a southern state that voted for Trump. So when you look at hacker news and encounter opinions that are different than your own it might seem like Hacker News exists in a bubble, but I think it's far more likely your life exists in a bubble that's stronger than hacker news.
> Your assessment of the median voter is being super distorted by the geographic layout of the US, btw. The median voter did not vote for a republican senator.
The median senate voter would have voted for a Republican but that's mostly because California and New York didn't have senate races this year.
