What are the three propositions Feldman says many people have come to about United States politics today, and what is the incredible mechanism that he says will help us deal with these things?

The three propositions that Feldsman says many people have come to know about Unites States politics are:

1. We are geographically localised in United States Politics

2. Unites States favoritism towards political parties (partisanship) are at their worst.

3. It is for a fact that there is nothing we can do about it.

Feldsmans says the last proposition is wrong .

Explanation:

The incredible mechanism that Feldsman says would help us deal with this things is the Constitution. The Constitution of the United States of America has be designed, formed and written in such a way that it can help us to achieve calmness thereby enabling us to manage disagreement among groups of people as well as helping us to deal with partisanship which is favoritism towards a particular political party.

The United States Constitution is the reason why something can be done about first two propositions.
