In general......people are stupid. A lot of folks simply don't care other than what the candidates actually say. They take these sayings at face value without ever researching on what positions the candidate has voted for in the past and their current stance on said issue. You cannot tell what a politician will do unless you look at their previous voting record which at least gives you a barometer of what they are all about.
I don't believe that it is beneficial for the vast majority of Americans when US policy is geared towards more war, runaway immigration(legal and illegal), massive energy consumption, no monetary reform policy, and huge bureaucracies that have proven time and time again to be inefficient and ineffective. No single candidate is going to deliver any of these until the American people wake up and demand these things, and to vote in candidates will do this type of thing.
As far as Europe goes, heh. At least we have some hope here in the US. Europe and its attitude depresses the shit outta me.
