1) The biggest problem in politics is that a huge percentage of white people are racist and would prefer to be poor if it means a black or hispanic person will also be just as poor as them, or hopefully more poor.
Thats really what it comes down to, and nobody is going to go say that on Live tv.
2) The second biggest problem is the right wing ecosystem. If I live in the middle of Nebraska, I typically have access to a ton of right wing radio stations and local news channel. I have to use youtube to find progressive or even centrist Democrat ideas, or cable news. If I dont have reliable internet or cable news, Im not even exposed to those ideas.
3) Third biggest problem is the actual framework of our political system. The electoral college was literally invented to give slaveowners more power wtih the 3/5ths of a person rule for black slaves. Id say 80% of white people arent even aware of this thanks to problem number 2. The electoral college and the senate are designed to give rural states more power. This is why they continually get there ass beat in the popular vote for both President and the Senate on a regular basis. The House of Representatives is also skewed because there is an artificial cap on the number of seats, and through gerrymandering, states destroy the integrity of your vote as well
Plenty more to go, here is good place for a break.
