I probably shouldn't be back here considering the shellacking I've taken in the last few days, but I have a few thoughts to the responses. For background I work at one of the worst COVID impacting hospitals in the U.S. It was awful and terrifying and pretty much everyone I know had family die. My thoughts are non anti-humanitarian, they are about process. I'm here for the debate not to talk down to anyone, but fire away.
Many of the responses quote one clause or another without an examination of application and the others mostly imply them. The Constitution is, by nature, a predominantly proscriptive document (@MachineShedFred) Indeed, some of the commentary is noting how many other clauses have been stretched beyond their meaning and using that as justification. The Necessary and Proper clause (well written @hey!) is about Congress' ability to write new laws, not a free-for-all. @Jellomizer, also well written, but this is not a law; and if Congress wants to declare war and buy weapons they can - but that is not what is happening.
I used to work for a company that reviewed their top 100 projects for the year, then (effectively) they gave each project a body and a dollar - nothing ever got finished. My current company prioritizes a few top projects, funds them, staffs them, drives them to completion. It is an as-kicking, but rewarding; we accomplish things now. The government is the last company, not the current one. The last COVID bill was something like 25% actually to COVID and 75% pet projects. The infrastructure bill is also something like 25% to infrastructure and 75% to pet projects. If you want to do pet projects, have the stones to do them, don't hide them in other bills. If Congress want's to declare war on COVID, DO, but let's not make every convoluted excuse to do whatever a president thinks is cool (regardless of party). The Constitution was about process and it seems like most of the arguments say we need to set process aside and do whatever we want. The Bill of Rights has suffered enough under that logic (by the GOV, not you here). That is what I'm not cool with.
