I don't see much references to "the swamp" anymore now that we have a sitting president doing a crypto grift. I thought dark money and mysterious figures pulling the strings is conspiracy worthy but I guess not when it's Trump.
Say what you will about "the swamp" (not a big fan myself), but as a metaphor it kinda works since a swamp may be noxious and filled with unsavory swamp creatures... but it's still an ecosystem where competition and co-evolution amongst these swamp species in response to external environmental changes would still be expected.
OR they aren’t ignorant, and are fully aware of things, and instead are scum.
