You’ve presented some very legitimate arguments.
However, I don’t think the founders ever intended for career politicians.
You sight the good work of Thomas Massie, Rand Paul, Jim Jordan, etc.
I believe that changing the culture and requiring fresh faces will naturally attract more constitutionally aligned actors.
I agree with your points on PAC money and localizing campaign funds.
Public Service was intended to be something we are called to when our unique voice is needed for the greater good of the country. Public Service should have a intrinsic cost to it. It is not a glorious job. It’s rigorous, painful work to operate within a beaurocracy.
