william jennings bryan no longer supported them after he lost the election.

the republicans took over the party platform after roosevelt became president.
members could not raise enough money for expenses.

Explanation:

The Populist Party (People's Party) aligned with the Democratic Party to support William Jennings Bryan in the 1896 presidential election. After his defeat, Bryan distanced himself from the Populists, and the party lost its key figure and momentum, leading to its collapse. The other options are incorrect: the party did address economic changes, Republicans did not co-opt their platform under Roosevelt, and funding issues were not the primary failure cause.

Answer:

William Jennings Bryan no longer supported them after he lost the election.
