I honestly don't know a ton about Taft's presidency, but what made him such a bad executive? I really should invest in some books about him, since on the surface, he's pretty interesting: only dual President/Supreme Court justice (which, even if it's inarguable that he was great there, seems completely at odds with the ostensible non-partisanship of the Supreme Court), Teddy Roosevelt's Bull Moose Presidential run was a somewhat direct outcome of his tenure, all on top of the many apocryphal stories about his girth. If you've got any recommendations for learning about his weakness as a President, I'd appreciate them.
