We have many options to achieve this purpose, Impeachment is not one of them. The purpose of impeachment is to remove a President, it has no other object. This we cannot do given the current political makeup of the Senate, therefore it is a completely irrational course.
The purpose of impeachment is to remove a President, it has no other object.
It can have other objectives.
In an earlier post you said impeachment was a political act. Now you are saying that it's purely technocratic.
It is not, and there is no reason why we should allow it to be.
With impeachment, we articulate a truthful message, we rally the people who don't like Obama and we send a message to the remaining people that Obama deserves to be impeached.
And I would add, we go after politically the Democrat senators in red states who vote against it.
In the alternative course of inaction, the opposite happens.
