How far can Theodore Roosevelt be seen as 'the greatest Progressive of them all'?

From the time he stepped into politics at the age of 23, he sought to change the way things were being handled. He exposed bribery that was taking place, and stood up to the the "special interests" that were taking place. Roosevelt wanted to put an end to the waste, inefficiency, corruption, and spoils system that ran rampant in government.

As President he increased inspection laws for food, drug and meat processes, he investigated child labor conditions, inactef employer liability laws, and laid the foundation for the modern administration state. Roosevelt also enacted graduated income and inheritance taxes, expanded the national park system, made wildlife refuges, he brought an end to the Russo-Kapanese war, and was the first American to be awarded the Nobel Peace Prize
