Roosevelt was elected to a full term in 1904 and promoted policies more to the left, despite growing opposition from Republican leaders. During his presidency, he groomed his close ally William Howard Taft to succeed him in the 1908 presidential election.
Roosevelt grew frustrated with Taft's conservatism and belatedly tried to win the 1912 Republican nomination for president. He failed, walked out, and founded the new Progressive Party. He ran in the 1912 presidential election and the split allowed the Democratic nominee Woodrow Wilson to win the election. Following the defeat, Roosevelt led a two-year expedition to the Amazon basin where he nearly died of tropical disease. During World War I, he criticized Wilson for keeping the country out of the war, and his offer to lead volunteers to France was rejected. Roosevelt considered running for president again in 1920, but his health continued to deteriorate and he died in 1919. Polls of historians and political scientists rank him as one of the greatest presidents in American history.
