@arabisouri, Your questions are fair and deserve a better response than I could give. The shortest version I can think of would take me days to ponder so I will skip much of what to say.
The U.S. Constitution guarantees every citizen the right to vote, if they choose to. Unfortunately most of our Congress has been seated for so long they no longer have ANY idea of what their Constituants want or need. Instead they all have their pockets open to the wealthiest and take routine payoffs for approximately 2% of our population.
As this continues to happen many become disillusioned with the process and simply quit voting, this further allows the "Incumbents" to further their search for wealth.
Our "News Media" was originally created to be a fair, non-partisan information clearing house (for lack of better description). They now exist solely on the propaganda that is paid for by the wealthiest 1% of our population.
Places like "Cambridge Analytica" have been formed to shape the opinions of the young adults to make them believe they DO NOT NEED TO VOTE to be "cool" since voting does not do any good anyway.
Some Social Media also attacks the majority of the voting public intimidating them to vote "their way".
Remember the opening where "Our Constitution Guarantees" to every citizen? This includes our military ersonel overseas and Embassy staff in other countries. Unfortunately most of these folks are heavily influenced by "Acts of Congress" and their "Commander in Chief".
So, I guess you could say our elections are all flawed to some extent and that NOT enough Voters are overly concerned with what is going on in the world.
Hope I didn't scare you with the abreviated answer... Mitch
