A cartoonish, mascot version of William Howard Taft, the 27th president of the United States, made his debut to Washington Nationals fans packed inside the Walter E. Washington Convention Center today. Taft was introduced as the fifth competitor in the Nationals’ fourth-inning Presidents Races, joining representations of George Washington, Thomas Jefferson, Abraham Lincoln, and the no-longer-long-suffering Theodore Roosevelt.

But the addition of Taft as the first non-Mount Rushmore president into the Nats’ daily sideshow came with a chunky historical inaccuracy: the team staff member wearing the Taft costume was quite slim, and there appeared to be no sign of any extra padding around the torso. Taft, as even the laziest students of U.S. history will recall, was the fattest person to ever occupy the White House, and perhaps no bit of presidential apocrypha is more famous than an incident in which the 300-plus-pound Ohioan got stuck in a bathtub.

Absent heft aside, the Nationals billed Taft—or “Bill,” as he’ll be called alongside George, Tom, Abe, and Teddy—as a natural choice. Not only did he succeed Roosevelt as president, he was the first president to throw a ceremonial first pitch at a Major League Baseball game with a lob from the Griffith Stadium grandstand before the first game of the Washington Senators’ 1910 season.

Fans at NatsFest seemed to take it in stride, even if the Nationals went against the advice offered by a DCist poll last season when rumors of a fifth racing president started to bubble up. In that two-round survey, fans ultimately chose Franklin Delano Roosevelt to join the pack, which would have prodded the Nats to get creative about the 32nd president’s use of a wheelchair. In fact, Taft finished in the middle of the pack in the first round of voting; he edged out Martin Van Buren, but still finished a few votes shy of Kang.

Still, the Taft mascot entered to applause and laughter, especially when the Roosevelt mascot walked out on stage.

“Whatever,” Nationals right fielder Jayson Werth said with a shrug. When told by another reporter that one fan had suggested that a (presumably) roly-poly Taft character could only win the dash around the warning track if Werth tackled the other four racers, he did not rule out the possibility. “It’s happened before.”
