Just look around. It’s easy to see that America is seething. From the Tea Party to the Occupy movement, voters are infuriated with the direction of the country. In itself, that’s not news. With the economy the way it is, that's hardly a surprise.
And Americans tend to take a personal interest in politics- despite the fact that only 54% of the population voted in the last presidential election. (And that's a high figure from previous elections too!)
Of course, politics in the US has never been known for its calm reflection and careful thoughtful approach. However, what seems to happening with each election cycle is becoming a matter of concern. No matter what the outcome, growing numbers of Americans are automatically rejecting the results. This in turn pushes the anger to the next level.
