It starts by Republicans keeping the school system balkanized into 50 different state curriculums, then they work to suppress the teaching of Critical Thinking Skills in as many state systems as possible. Without CTS, students develop some other petsonal random form of chaotic thinking.
Then they get out of school, and somewhere along the line they get introduced to the Conservative Propaganda Machine, which knows how to manipulate the minds of those who were deliberately never taught to think properly.
The best solutions would be a single responsible FEDERAL public school curriculum in all 50 states, that focuses on teaching and honing Critical Thinking Skills, with a section on recognizing and resisting propaganda. 2+2=4 in every state in America, Cat is spelled C-A-T everywhere in America. We don't need 50 state curriculums. You want to DOGE the government? Start with streamlining the educational system so we aren't reinventing the wheel 50 times, often by states that don't know a wheel should be round, or want to make it square because it pisses off the Libz.
After that, we need regulations on political propaganda and disingenuous political speech. We have truth in advertising laws, and they should apply to political speech as well. After all, political campaigns are just marketing campaigns for a product (the candidate), and should be expected to be as accurate and truthful as any other advertising.
