Actually, the problem is money. If you want to be a serious candidate for national political office, you’ll need a lot of money & a lot of powerful friends. These folks expect something in exchange for their support, and it won’t be a speech on civil ethics.
The Founding Fathers engineered a government designed to address the ills of the systems in that age, such as monarchies and traditional democracies. The scenario of economically influential business entities directing the affairs of government is not one that’s happened in the way we see now, with Senators and Admirals on corporate boards of firms supplying the government while also employing voters . We don’t even bat an eye at the headlines anymore; half the US Navy Pacific admiralty is under investigation for bribery and few publicly know about it. The SecDef Office is basically a financial conveyor belt for defense contractors.
I could keep typing, but this is why the Mueller Report is a red herring; if such an investigative effort was made to every career politician in DC , they’d all be found to be just as dirty as Trump is. Including Pelosi and those who’d be charged to vote for impeachment proceedings.
What is the common political platform of Democrats and Republicans?
Money- and getting more of it.
