What was the outcome of the 1904 US Presidential election?The 1904 United States presidential election resulted in a decisive victory for the incumbent Republican President Theodore Roosevelt. He defeated the Democratic nominee, Alton B. Parker, by a wide margin in both the popular vote (56.4% to 37.6%) and the Electoral College (336 to 140). Roosevelt's win marked his first full term in office after succeeding the assassinated William McKinley in 1901.
