Yeah you have some points there.

The media usually force feeds us our choices for Republican or Democrat. Usually I think they are both candidates who will toe the line, so the media is fine with either. It is during the nominee process that you see this media attack crap occur to kill off candidates they don't want to be the nominee. "X is not electable". Sure he is not electable, because you won't let us know about him. You're telling us right there who we can/cannot vote for.

As to normal presidents.

How wise is it to continually have presidents that are trained to lie, and to represent their client even when the client is guilty?

What would you expect someone to do with those skills once they are president?

Yet that is a common type of president we elect. A skilled liar, I mean lawyer, and if they are charismatic that is better.

Yet who is their client? It is not the people.
