3 step plan to fix the US political system

The founding fathers had already thought about your concerns and have already addresses them. The House can passed flawed legislature which has been heavily influenced by money, but if the Senate doesn't see the merit in the Bill, they will simply reject it, whether the President is for it, whether the House is for it, and whether the big money interests are for it if it is bad for their constituency. I am not concerned with the Senate passing more laws. More bad legislature pushed through the system does not equal better government.

There are extremists in all state legislatures, but they are not going to be, and historically haven't been the types of people the state legislatures have sent to Washington DC. In the past before the 17th Amendment, the Senate was filled almost completely with moderates. And even if one or two bomb throwers get through the state legislature, then who cares? The Senate still has 100 people with 100 divergent interests. As for a Senator doing what the state legislature wants, I am pretty sure that wasn't historically a problem, and I do not see that becoming a problem today. The Senators are insulated from the whims of individuals by being given a six year term. A Senator could conceivably vote his conscience for 5 years and then become a toady his last year and still get re-elected.

Contrast that to what we have today where money is a corrupting influence in both the House and the Senate. The people are still powerless to impeach a Senator because there exists no option to do so in the 17th Amendment. You elect him, your stuck with him for six years no matter what. And with the corruption of money, we still get left and right winged extremists in the Senate and the most partisan Congress anyone has ever seen. If you like the status quo, then you need to think about getting rich.
