We are starting to see headlines like these.

Bond investor Gundlach said that the biggest risk to the market in 2020 was the possibility of Sanders becoming president.

Longtime hedge fund manager Stanley Druckenmiller said something similar last summer, warning that stocks could plummet if Sanders is elected president.

“If Bernie Sanders became president, I think stock prices should be 30% to 40% lower than they are now,” he said in June.

The thing is that this is very likely to be true.
I don't say this lightly.
However, something is missing from this analysis. The most important thing.

That something is that the stock market is massively overvalued.
Right now the stock market is a bubble in search of a pin.

Using the price-to-earnings metric — which measures a company’s current share price relative to its per-share earnings — shows the S&P 500 is trading 24.37 times forward earnings.

To put that in perspective, the average ratio in the last five years was 16.7, and just under 15 in the last decade.
...
The price-to-sales ratio looks at a company’s market capitalization and divides it by the company’s revenue in the last 12 months. A lower P/S ratio usually leads to a stronger investment.

And this is where the overvalued picture really begins to get clear.

In short, Davis sees market prices falling.

Davis added the S&P 500 “could be overstating earnings due to buybacks and other financial engineering of profits.” Over the last five years, S&P 500 earnings have topped corporate profits.
“P/E ratios are some 80% above the long-term norm,” Davis said.

If you take a long-term Post-WWII look at the stock market, the average P/E ratio is closer to 12. Which means stocks are priced to absolute perfection right now.
So guess what happens when perfection doesn't happen?

Bernie is not the real danger to the stock market.
Corporate America has two critical problems that has nothing to do with elections.

1) Losing money

The combination of forces has pushed the percentage of listed companies in the U.S. losing money over 12 months to close to 40%, its highest level since the late 1990s outside of postrecession periods.
...Investor tolerance of losses shows up most obviously in new issues, where about three-quarters of IPOs were made by loss-making companies last year, according to University of Florida finance professor Jay Ritter.

It doesn't take a genius to know that investors will eventually sell companies that can't make a profit (i.e. Uber, Tesla, Netflix).

2) Way too much debt

According to the Fed’s meeting summary, some from the bank are worried that its own policies will continue fueling the corporate debt bubble and make the next US recession even more severe.
...The Fed isn’t the only one to sound the alarm on the worrying amount of debt US businesses have racked up while interest rates were low.

Corporate debt has risen by 50% since the financial crisis, bringing the grand total to just under $10 trillion.
Over the next five or six years, about half of that debt is going to mature, the result of which could be catastrophic. Many US corporations that used cheap debt to finance buybacks and acquisitions will likely have to refinance at higher rates, putting a strain on corporate earnings and, in turn, share prices.

Let's add all of this up.

a) Corporations are swimming in debt, and
b) have trouble making profits, while
c) stock market prices are ridiculously expensive.

Yet, when stocks finally begin falling back to Earth, it'll all be because Bernie won a couple primaries. So that's why you must vote for a corporate centrist.

Mark my words. You WILL hear this bullsh*t spewing from the mouths of "very serious people" on cable news.
