We're at university together <a href=" http://www.melisse.fr/edouard-ferlet/ ">purdue triangle viagra yg</a> Systems like our own have a broad tendency toward instability and partisan conflict because a democratically elected executive can come from one party and a democratically elected legislature from another. Both sides end up having control over some levers of power, a claim to be carrying out the will of the public, and incentives that point in opposite directions. That's very different than the kind of system you see in, say, the United Kingdom, where only one party controls the government at any given time.
