Invertebrate Politics 

The inability of any given political agent to actually respect, comment on or support any position outside of established party lines despite being fundamentally offensive to personal ideology.

So, we should just ignore massive national debt, the endorsement of white nationalism and ridiculous, weaponized tariff impositions that are ultimately paid by US consumers?
Of course! That's how Invertebrate Politics work...it'll be fine. Right?
