Washington — PITY Poppy.

When I went down to Houston a few years ago to eat pizza with the former president, he was his usual gracious self, speaking fondly about President Obama and his new pal Bill Clinton.

But there was one person who got dismissed with a brusque obscenity: Donald Trump.

It was at the height of Trump’s birther madness and Bush was disgusted by it.

So I can only imagine 41’s dismay and disbelief — and acid flashbacks to spoiler Ross Perot — now that Trump has popped up to block the path of the son who Poppy desperately wants to see as 45, restoring the family name after 43’s spiral.

The New York wheeler-dealer, who held a fund-raiser at his Trump Tower apartment for gubernatorial candidate Jeb at Poppy’s request back in 1997, has had a devastating and disorienting effect on Jeb’s presidential candidacy.
