Peru may elect a Marxist President!

Peru will most likely elect a leftist-marxist president, who plans to nationalize the mining industry. What impact would the spread of communism have on the US stock market?

As of now, 96% of all the votes have been tallied by the (ONPE) - the Office of Electoral Process. This gives Pedro Castillo the victory with 50.288% vs Keiko Fujimori 49.712%. Super tight spreads.
