Bill Moyers has reminded us. The president has greatly extended the claims for power for the president. That is a fundamental challenge to the checks and balances our constitution provides. He will hand over to his successor a "tool box" full of very new powers for the presidency that will not benefit the country.
Moyer's guest, Fein and Nichols, one who drew up the articles of impreachment and the other with the Nation agree: the Congress has the obligation to protect the country and our constitution. They are failing. They care more about their parties and their careers than about the country.
It is very hard to imagine a failure for the legislature that is worse.
