Christie could learn from Taft
It's unclear whether Christie would be the heaviest president in American history, but he would certainly share one of the top two spots with William Howard Taft, who served as our 27th president from 1909 to 1913. And though that was a long time ago, in a much different era, there may be a thing or two that Christie can learn from Taft's experience.
Perhaps the most important lesson is that Taft — who probably never got stuck in a bathtub, but did once travel to the Panama Canal with a tailor-made tub that was reportedly "the largest ever manufactured" — embraced his ample size with good humor.
