But remember it was Bryan that was considered "radically liberal" at the time. He was the Democrat that first tried to make it the "Working man's" party.
Well if by "working man's party" you mean the party of farmers in the Great Plains who had a large influence on the Democratic party then yes. However if you mean working man in its normal context Bryan really wasn't that different from the norm of the late 19th century. His main idea was the silver standard which would help farmers in the west since they were usually constantly in debt and the higher inflation of silver would help reduce their debt. However for anyone who is not connected to the farming industry, everyone from factory workers to JP Morgan, would be even worse off from a silver standard than they were under the gold standard.
You really don't get what we see as American liberalism in its modern form until the progressive movement of the early 20th century and the Socialist and labour movements of the late 19th and early 20th century. Even then most of these were concentrated in the Republican Party until the New Deal in the Progressive and late LaFollette wing of the party. It wasn't until Roosevelt's New Deal that the Democrats really become the party of the left though with the laissez-faire policies of Coolidge this somewhat happened during the 20's, when LaFollette was marginalized within the party. However Hoover was a Republican cut much more from the old progressive mold, though not as far left as LaFollette, but you know what happened to him. So basically the New Deal was the first time when the eocnomic positions of the parties shift into their modern form.
