Sept 26 (Reuters) - Wall Street was set to open lower on Monday, with investors gearing up for the first debate between U.S. presidential candidates Hillary Clinton and Donald Trump.

“The polls have both candidates neck-to-neck. The debates might increase the lead of one over the other and that’s what the market is fearful of,” said Peter Cardillo, chief market economist at First Standard Financial in New York.
