 George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt, mascots compete.A William Howard Taft mascot also raced from 2013 to 2016, as did a Calvin Coolidge mascot in 2015 and a Herbert Hoover mascot in 2016; as of 2017, the Taft, Coolidge, and Hoover mascots had "retired to Florida" to race only in Nationals spring training games.As a running joke, Teddy Roosevelt did not win from the beginning of the Presidents Race in 2006 until the Nationals made the playoffs for the first time in 2012.
