I am not registered as a member of any political party. Given my interest in politics it may seem an unlikely scenario. Let me tell you my reasoning.
The Republican Party historically in the 20th century was the party supporting business. They fought for lower taxes and less regulation. Who can be opposed to those objectives? Then the conservative religious groups evolved inside the G.O.P. Instead of being the business party they became the party of Evangelical Christians and other orthodox religious groups that put their religious beliefs ahead of business and the rights of non-believers. Today, thanks to Donald Trump, the G.O.P. has become the party concerned with helping the working classes of the country and the party of the extreme right wing (alt-right/neo-Nazi) hate groups. This is not a pretty picture.
Sadly the Democratic Party is no longer the party of the working class and middle class America. Extreme left wing socialists have become the driving force within the party. Senator Bernie Sanders has become a leader of this socialist perspective. America does have some socialist services but not to the level that the left wing aspires to bring to America. Social Security, Medicare, Medicaid, and welfare for the needy are all socialist programs but I do not support government ownership of businesses that should be operated privately (car manufacturing companies, aircraft manufacturers, etc.).
Third parties have had an inconsequential impact on American politics.
I am left with selecting candidates that have said or done something that catches my attention. I voted for both Democrats and Republicans in November. Some races were left unmarked for any candidate.
Donald Trump appears to be a thin skinned man who takes every slight as a major insult to him. How will he conduct himself as president? His behavior as a candidate has not changed since he won the election. The only thing that might stop him from starting a nuclear war might be the decisions of a wiser military.
How did America get itself into such a predicament?
