Since announcing his presidential candidacy in June, Jeb Bush has made clear his distaste for officials who trade on their connections.

He has assailed the revolving-door culture of Washington, calling for “a little bit of a recession” there to thin the ranks of the permanent political class. He has proposed a strict six-year ban on lobbying for departing members of the House and the Senate.

And he has shown little patience for the euphemisms of the Capitol, using derisive air quotes to describe “government relations” and “government affairs” experts.

“It’s easy for elected officials to lay out standards of performance for others,” Mr. Bush said during a July speech in Tallahassee, where he worked for eight years as Florida’s governor. “But what are the high standards worth if they’re not applied to themselves?”
