This cartoon is over a month old, but just as true today as yesterday. It will be true tomorrow too. Investing and trading is primarily about fundamentals and technicals but if you're smart you never forget the political landscape and how it will help or hinder the businesses making up the market. An interesting fellow, now departed, even made a business out of educating people about this political/economic interaction that he called Polyconomics.
