Answer: William Jennings Bryan
Explanation:
William Jennings Bryan was a Nebraska politician who was nominated by his party, the Democratic party, to be their Presidential nominee in 1896 after he gave a rousing speech which today is known as the Cross of Gold speech in support of the bimetal/silver standard. 
The standard called for the use of both gold and silver to back the American dollar as opposed to using just gold and was strongly supported by the lower and some middle class. The standard however would have brought high inflation as well as making it harder for the US to trade with other countries. 
William Jennings lost the election and the US continued with the gold standard.
