We've also allowed the Federal government to become so powerful in our lives via regulation, subsides, entitlements, etc that Senators and Representatives have become power brokers instead of citizens.
We've allowed government positions to become far more important and lucrative than those who framed the Constitution intended.
Term limits. Walking skeletons like Feinstein, Pelosi, Biden, McConnell shouldn't be serving for decade after decade so they become so powerful.
The Constitution called for citizen representation but we've allowed and created entire families whose "business" is politics.
As you say, in the name of keeping the power in our tribe, we feel we MUST vote for our people.
Term limits. The Federal government should not be anywhere near as intrusive as we've grown accustomed to because we've entrenched these people in the bubble that is DC.
