I think people have mistaken the reason why tis happens, and it has nothing to do with politics, or even the level of education per say.
What happens when you pursue a higher education is that you expose yourself to more knowledge, ideas, thoughts, and experiences with different people, cultures, mindsets, etc.
You learn how to think at a higher level as well.
The less educated you are, typically, the less exposure to the world you have, so your stay at whatever level you reach.
We see this phenomena too with people who travel as opposed to those who don't.
The more a person travels, just like people with more education, the more ideologically left they tend to become, because they're busting out of that bubble they're in.
There's learning more about the world and experiencing more.
It's not a left or right thing - it's an exposure and experience thing.
California, this November 4th, the whole country is counting on you.
Prop 50 puts our elections back on a level playing field, preserves independent redistricting over the long term, and lets the people decide.
So return your ballot today. Vote yes on 50.

They ain't give a f*ck about that sh*t. ... I got $50M. I ain't about to go to jail for these little dumb a** pills. It just let you know how pure he was. He didn't know no better. That's what f*cked me up the most. You didn't even have to do that." - @gherbo
