was Teddy Roosevelt a socialist?

He was a Progressive reformer who sought to move the dominant Republican Party into the Progressive camp. He distrusted wealthy businessmen and dissolved forty monopolistic corporations as a "trust buster". He was clear, however, to show he did not disagree with trusts and capitalism in principle but was only against corrupt, illegal practices. His "Square Deal" promised a fair shake for both the average citizen (through regulation of railroad rates and pure food and drugs) and the businessmen. He was the first U.S. president to call for universal health care and national health insurance.[5][6] As an outdoorsman, he promoted the conservation movement, emphasizing efficient use of natural resources. After 1906 he attacked big business and suggested the courts were biased against labor unions. In 1910, he broke with his friend and anointed successor William Howard Taft, but lost the Republican nomination to Taft and ran in the 1912 election on his own one-time Bull Moose ticket. He beat Taft in the popular vote and pulled so many Progressives out of the Republican Party that Democrat Woodrow Wilson won in 1912, and the conservative faction took control of the Republican Party for the next two decades.

Roosevelt negotiated for the U.S. to take control of the Panama Canal and its construction in 1904; he felt the Canal's completion was his most important and historically significant international achievement. He was the first American to be awarded the Nobel Prize, winning its Peace Prize in 1906, for negotiating the peace in the Russo-Japanese War.

Historian Thomas Bailey, who disagreed with Roosevelt's policies, nevertheless concluded, "Roosevelt was a great personality, a great activist, a great preacher of the moralities, a great controversialist, a great showman. He dominated his era as he dominated conversations....the masses loved him; he proved to be a great popular idol and a great vote getter."[7] His image stands alongside Washington, Jefferson and Lincoln on Mount Rushmore. Roosevelt has been consistently ranked by scholars as one of the greatest U.S. Presidents.
