After disappointing finishes in presidential nominating contests in Iowa, New Hampshire and South Carolina, Jeb Bush suspended his campaign for president Saturday night. It was the end of a run that had seemed doomed for months: countless gaffes, merciless attacks from the likes of Donald Trump, seemingly limitless spending from a superPAC he couldn't control with horrible returns from those investments and perhaps above all, a candidate who seemed uncomfortable on the trail at best, and at worst, frustrated and unhappy. Already, the post-mortems are almost writing themselves.
