Jeb Bush was not in the business of planning and discussing national security, intelligence, secret and/or confidential matters. He was not the nation's top diplomat. And his work in Florida on highway speed limits or grants for play ground equipment was not the target of high stakes secret information.
Finally, Jeb Bush (like everyone else but Hillary) did conduct much of his business over his State email.
It takes a degree of hutzpuh (or lunacy) to compare Hillary's acts with Jeb's...rather like someone telling us Hillary may have robbed a bank but they located Jeb, a Republican pick-pocket.
