Do you think it is important to maintain a system of checks and balance in America?

I do not think Congress represents the American people. I think they represent the Lobbyist and the elite. I think the Middle Class has no representation.
The Republicans and Democrats represent extreme Ideologies. The Republicans are to far to the right and the Democrats are to far to the left. No one seems to be moderate or have any common sense. No one does what is best for the American working people.
Isn’t that why we were suppose to have checks and balances? I thought the checks and balance were suppose to prevent the extremes from taking over.
