Matt Forney really lays it into Jabe in this piece at RoK. Jeb is truly not the right candidate for this (or any) election cycle:
The Bush clan has always been America’s equivalent of the Hapsburgs, changing ideology, religion and even ethnicity in their quest for power. Prescott Bush, the dynasty’s patriarch, was a liberal senator from Connecticut who aligned himself with Nelson Rockefeller; George H.W. attached himself like a remora to Reagan after flaming out in the 1980 presidential primary; Dubya hired a voice coach and bought a ranch so he could pretend to be a Christian hick from Texas.
Unfortunately, Jeb Bush is the worst possible man to carry the Bush family’s torch. Beyond the gargantuan amounts of baggage that the Bush name has accumulated, Jeb is temperamentally better suited to run for the school board then for president. The twin themes of this year’s election are nationalism and economic ruin, which both Donald Trumpand Bernie Sanders have picked up on, explaining their grassroots success. The closest thing Jeb has to run on is a nostalgia for the Dubya years that doesn’t exist.
I would feel bad for the guy if his ideology on globalism wasn’t a threat to the well being of every American citizen, except perhaps the Walton clan. But he very much has the feel of a guy going through the motions, whose family put him up to it, and who has no real fire to be President.
