If Donald Trump does not accept the verdict of the American vote in November, Jim Cramer fears it could be a major blow to stocks.
"The idea of this election dragging on past Election Day is a nightmare for investors," the "Mad Money" host said.
There is so much money waiting on the sidelines that is waiting to get back into the stock market. But if Trump contests the vote, Cramer says the market won't be able to mount an early November rally that investors expect once the election is over.
While Trump did say on Thursday he would accept the results of a decisive vote in his favor, Cramer said investors need to watch to see if the race will be close enough for Trump to contest. The uncertainty generated from that could hold back the averages.
