Best. Labored metaphor. Ever.

From some RW site, via Sadly, No:

The political left in America is like a deranged passenger on a jetliner who repeatedly attempts to storm the flight deck and crash the plane, but who the crew and other travelers are limited in their ability to restrain due to obscure regulations (whose full implications were unforeseen when they were implemented) which give the unhinged would-be saboteur the right to move about the cabin freely.

"Liberalism is a mental disorder" mixed with a delightful dash of "look at how clever I am." Charming.
