GWB said he would not vote for Trump who won the primary fair and square. Jeb and Kasich ignored their pledge to support the nominee.
The Bush family has an enormous sense of entitlement. Jeb had the hubris to run for President after both a father and brother had occupied the WH. And the fact is the Bush family did a terrible job of running this country and they unraveled the Reagan legacy. Neither Bush 41 or Bush 43 was a conservative.
Mostly agree with you on the family’s dynastic performance.
Still, its unusual for the formalities to not be observed, even if there is tension. Their choice; we get to comment.
