I think in order to be eligible to vote, they should have a high school degree or GED, and in high school they should require Politics 101 or something similar, for basic education and understanding in politics. I understand that politics isn't for everyone and that is fine, but I think that a basic understanding for politics would help people vote better, which will lead to healthier communities.
So I would vote: [X] GED or high school diploma
Having a Degree or Qualifications of any sort in our day and age no longer proof one's intelligence / capability / Domestic ( Geo ) Political Acumen.
Whatever you mentioned used to be the case (barely) 20 or 30 years back whereby decently educated citizens are slightly more capable to choose and select their representatives.
But this doesn't work in the United States since your top guy, congress etc etc make decisions that are heavily influenced by lobbies.
And in order to move , at times, solid bills or policies that will improve the lives of citizens, one party have to agree to some ridiculous BS from their opposition so that there are enough signatures to get the bill, policy , law enacted or passed.
For Example....
Republican wants to pass a Bill that Jail Pedos and trafficking of minors for life.
Democrats... sure ...... Let's add other clauses that is unrelated to the above.... Transgender get to read story books to children and promote their lifestyle at least 10 hours per week in schools and this is compulsory.
or
Democrats wants to pass a bill to improve Healthcare , Veteran care , regulate foreign lobbies etc etc
Republicans....sure Let's add an unrelated clause to the above...... Agricultural companies are now allowed to procure African, Indians and Chinese that are non American Citizens to pick cotton in the fields and sing.
Any insubordination from such " workers " can be punished by said owner in the form of tying them to a tree and lashing them with a whip not more than 30 times per week.
The above ridiculous BS is for dramatic effect and to showcase how ridiculous some of these bills are.
