Arguably, the philosophical fault line in American politics centers on which entity is distrusted and feared most; government or big business. Note that this has nothing to do with either side believing government is wonderful, clever, or even something positive. In a non-combative setting those on the left are as willing to criticize the ineffectiveness, arrogance and stupidity of government bureaucracy as those on the right.
In most elections voters tend to vote against a candidate more so than they vote for the candidate’s opponent. It is the old lesser of two evils dilemma. Not surprisingly, this reflects the larger philosophical contest. At issue is not whether a governmental approach is good or bad; or whether the free market approach is good or bad; in the minds of many voters the question is which is worse.
