@bobsal u1553115,
The real issue is that American voters are clueless, and their votes are overwhelming in elections. Until that changes, the usefulness of voting doesn't exist.
As you have pointed out, the American voters rate congress at 11% approval rating, then turn around and vote them back in! What kind of idiocy is that?
1. The US economy is the only one still recovering well from the Great Recession; better than Europe or China.
2. Millions more now have health insurance.
3. The majority of people now have jobs.
4. Most have recovered their loss from the Great Recession.
5. People are buying more cars and homes.
The American voter than turns around the elects into office the very party that has voted no to job creating legislation, tried to take away their health insurance, control women's body and health care, and deny any minimum wage increases.
Where's the logic - if there ever was one?
