Which of the primary features of grassroots Progressivism was the most essential to the continued growth and success of the reformist movement? Why?

Explanation:

The primary features of grassroots Progressivism that was most essential to the continued growth and success of the reformist movement would be that most strove for a perfection of political participation  for those considered “unfit” on account of health, education, or race. Progressives also agreed that democracy had to be balanced with an emphasis on efficiency, a reliance on science and technology, and deference to the expertise of professions. They repudiated party politics but looked to government to regulate the modern market economy. And they saw themselves as the agents of social justice and reform, as well as the stewards and guides of workers and the urban poor. Often, reformers’ convictions and faith in their own expertise led them to dismiss the voices of the very people they sought to help. The expressions of these Progressive principles developed at the grassroots level. It was not until Theodore Roosevelt unexpectedly became president in 1901 that the federal government would engage in Progressive reforms. Before the, Progressivism was work done by the people, for the people. What knit Progressives together was the feeling that the country was moving at a dangerous pace in a dangerous direction and required the efforts of everyday Americans to help put it back on track.
