The Senate advised and consented not to consider the nomination in an election year. Legal. With Barrett they advised and consented to consider the nomination. Legal. Moral? Not much.
Here's your logic:
1 - Republicans are wrong.
2 - My proof: https://www.archives.gov/founding-docs/constitution-transcript
3 - Democrats are allowed to be wrong too.
All you are doing is pushing tit-for-tat partisan politics like the Republicans are doing. There's a reason why 70% of Americans aren't Democrats and why 70% of Americans aren't Republicans. Both parties suck ass and serve themselves first, not the American public.
No, that is not advice and consent. That's like a jury saying 'we refuse to vote'.
