Just read her wikipedia page - as I'm not from the US I've been mostly treating US politics as a bad comedy show for the last two decades or so, and even though she's vice president she was too much of a side character to register.

The one thing that did rech me over there was that she's a bad candidate as VP as she'll erect a police state when biden dies. After reading her bio I can't find problems there, though. I disagree with some details - like seeking life imprisonment - but can give her a pass due to the environment she's operating in which probably wouldn't allow anything else (if you're confused: all convicts should undergo rehabilitation attempts with goal of release. If you stay locked up it'll be due to you still posing a danger to society, in which case you still get more privileges than a prisoner as at that stage it is considered a mental health issue, and treating you as prisoner for that would be a human rights violation).

For sticking to not seeking death penalty she deserves respect, though, and generally she seemed to be focused on putting actual criminals to prison.
