There is no way Janet Yellen will raise rates before the election. I don't know if you recall but, the FED has been vocal about raising rates multiple times last year. The only time they raised it was at the end of the year, the stock market crashed in January to it's lowest point in years!
Following the stock market crash, the precious metals have rallied due to loss of confidence in the US economy. If the FED raises rates, it's going to implode the market, and shoot Gold and Silver to the moon. I presume the FED will drop helicopter money before changing the interest rates. Which I think it will be dropped another .25 or even to negative territory.
