If Jeb Bush were Jeb Jones or Jeb Johnson, he might be a George Pataki or Jim Gilmore—an insignificant, if not irrelevant, former governor seeking the Republican nomination. But he’s a Bush—the third to run for president—and that comes with “free stuff”—the unearned advantage of dynastic ties that will always keep you from becoming Jeb Nobody. And he’s had that leg up since well before he made his presidential run official. Jeb entered the race with checks from Bush family donors and help from Bush family advisers. Indeed, his super PAC raised massive sums in the first few months of the year, almost all on the strength and reliability of his name.
