Liberals Make Messes

I have a hypothesis that conservatives are forever cleaning up messes made by liberals.

I have observed that there is always a big mess (bottles, can, tissues, paper scraps, etc.) after liberals hold a political rally, but there is never a mess after conservatives hold a rally.

And certainly this hypothesis is true on the national and state-wide political stages, where the liberals in charge are making huge messes that only conservative governments can begin to clean up (and it will take decades).

Does this hypothesis also apply to families, small businesses, and other organizations?
