Keep putting RINOS in positions of power and see how many conservative Republican votes you get.
The problems with our nation stems from the accelerating concentration of power in fewer and fewer hands. This problem cannot be cured by sending “good” men and women to DC.
Recent events also show that the exec, congress, courts no longer serve their constitutional purposes. So the question that addresses the nub of the problem is, “How do we change the institutions such that men's personal interests coincide with the public good?”
This problem isn't new; it was known in 1787. It is why the Framers designed such a complex system of powers divided among the people, states, and the government they created.
Our fate is sealed unless and until power is diffused once again across the states.
That means returning the senate to the states. When senators guard the interests of their states, when they are responsible to a few hundred attentive legislators instead of millions of low info voters with the cognitive skills of an MSNBC host, it will be in the interest of senators to stop and reverse the accumulation of power in DC.
There is no alternative.
Article V before we can't.
