These circumstances are possible in today's election because of the shift from the past traditional views of both parties to current push towards the real interests of today's electoral classes. The change of views has been small in the case of Hillary Clinton and the Democrats, however, and dramatic in the case of Donald Trump.
The movement away from traditional views has facilitated a policy realignment that is significantly different than those of past years, creating uncertainty as people decide which party they fall under. The change in policies has been made possible for the Republican party because of Donald Trump's independence from donor's money, as he has rallied his voters completely from his own pocket, which is why Trump's ideas seem so far fetched. The result has been a fall in the traditional conservatism of the Republican party, as Trump is creating his own ideas and beliefs. However, the traditional Democratic party views have simply shifted in the past few decades. This was shown in this year's Democratic primary elections, as traditionalist, Jim Webb, was out of place among Bernie Sanders and Hillary Clinton. The destruction of traditionalist views have facilitated uncertainty among voters as they decided who they will vote for, which also destroys the fine line that once separated these classes.
As the policy changes continue to adapt throughout the next few decades, the beliefs of each party will change even more. As parties' views change, American citizens will become more and more divided, creating chaos as well as uncertainty. The future of American politics may involve new political classes, the destruction of our current ones, or the continuation of political realignment.
