But would W J Bryan be the first Democrat to be a little more liberal than Democrats before him? or was Cleveland a liberal? What was W J Bryan and Cleveland's position on Civil Rights?
The term "liberal" in its modern US definition is not applicable to politics of that era.
Bryan certainly was what you'd today call an economic liberal (while Cleveland was what I, coming from Europe, would call one.
)
Both were anti-imperialist - indeed on that issue Cleveland would be about as far left as FreedomBurns.
On the issue of Black's Civil Rights, the Democratic Party of the era was utterly horrible. The Jim Crow segregation laws to be dismantled in the 60s were mostly passed during this era and into the 1920s.
Parts of the Bryan wing of the Democratic Party, and the Populists of 1892, supported Civil Rights positions on issues such as candidate selection (the primary was an invention of the era), votes for women, the death penalty, though - although, in the west, such support was also found among some Republicans.
No. In fact, it's safe to say he was less conservative than any of the 1881-1901 Republican presidents, in this respect as in others. Less conservative than the next two Republican presidents after him, as well.
