A couple of points about this article.
First, USA used to have a "tradition" that when a politician crossed a certain moral line, that politician was drummed out of public office--not by the constitution, but by public (and eventually party) pressure. That political force seems to be lost in both parties these days.
Second, Ms. Shelton alludes to the difficulty of average people participating in politics. There are many good people out there who would do a wonderful job, but can't afford the price of time and money.
I do have an ulterior motive on Medium. I'm trying to promote an alternative system of democratic governance. It is called "Tiered Democratic Governance". A 20 minute essay can be found here:
The TDG will address the first flaw with its annual election. If an elected representative is found in a compromising situation, he/she probably won't be elected any more. If he/she remain elected, it is unlikely he/she will rise any higher than they already are. There is no hiding under the banner of a political party to get elected in the TDG.
The second flaw is addressed by the TDG does not require any campaigning. So there is no campaign funds to raise, no speeches or door knocking. All that is needed is good rapport with one's neighbors. In essence, the TDG elects people who have proven some character and competence with people who see them often.
I invite you to read the 20-minute essay of the TDG. If you like that approach , there are links to my book.
