Makes me think we need to start thinking changing a law. Makes me think we only need one term Senators and Congress critters. They wouldn't be so apt to stick their fingers up in the air to see which way the wind is blowing if they were only there for one term.
You are both right, and wrong.
Congress was designed to be heavily but not decisively influenced by which way the wind was blowing.
The clever designers knew very well what the office-seeking class was all about, and the two-year House term was meant to create a body with their fingers constantly in the air. This is actually a good thing, and it's why, BTW, the House is stronger on war issues than the Senate right now.
The Senate, OTOH, was destroyed by the Seventeenth Amendment and has become a body of "super-congressmen" rather than the ambassadors from the States they were intended to be.
Running as an at-large Congressman from a whole state for a six-year term REQUIRES such a huge investment that all, or nearly all, of them are wealthy. And like all wealthy people, they all have a healthy regard for protecting their investments.
Your real problem is with the Senate, and I think that a term-limited Senate would be better than what we have now, but not as good as a return to an appointed Senate would be.
