I don't want a dictatorship, but if you think our politicians are actually representing their constituents views while introducing laws and voting on them, you are delusional at best. The Modern Politician will bend whichever way gets him or her the best deal (read $$$, IE; Vacations, Fancy Cars, Boats, Apartments, Houses, etc.).
It would seem that the modern politician gets into politics for the money. That they receive via kickbacks and campaign contributions for swaying the vote the way the lobbyists, corporations, and others with the monetary means to influence the law in their favor.
It has not been "For the people, by the people" for nearly a century, now. Certainly not in my lifetime.
