1 the system of ropes, cables, or chains employed to support a ship's masts ( standing rigging ) and to control or set the yards and sails ( running rigging ).
2 the ropes and wires supporting the structure of an airship, biplane, hang glider, or parachute.
That's the first definition of the word, and while it makes sense that a seagoing chappie like Mister Terrimp would have a fascination with all things nautical, but it's not my guess that he has been crabbing about the ropes, cables or chains supporting a ship's mast. Nor is it likely that he is worried about the wires supporting the structure of an airship. No, the rigging Mister Cheddar is referring to is that much more despicable kind: verb - manage or conduct (something) fraudulently so as to produce a result or situation that is advantageous to a particular person.
Usually, it's a sporting event that people get upset about, since elections are so carefully watched and monitored. Like the "Phantom Punch" that Muhammad Ali used to knock out Sonny Liston in 1965, Or maybe it's even further back, like the Fall Classic of 1919, when the Chicago White Sox decided to put the fix in on the World Series, turning their pale hose black for all time. In some ways, rigging is a peculiarly American institution, both from the observing and participating side. It was, or will be, Captain James T. Kirk, from Iowa, who gained fame as a Starfleet cadet by changing the parameters of the No-Win Scenario: The Kobayashi Maru. He changed them so he could win. A born leader.
Which brings us back to Donald T. Krump. His insistence straight along that the process in which he has had so much success, first in the primaries, at the convention, and now in the general election, is rigged against him certainly holds less water than if he had been booted out in the first round or two. Instead, he seems to be experiencing a great deal of success, especially when you believe just how awesome the odds are stacked against him. How can a seventy year old white billionaire expect to get a fair shake in this country?
I dunno. I guess it must really be rigged.
