I would still welcome a primary challenger against her from the left, since her 2020 presidential campaign shows that she isn’t actually principled about her beliefs (and I would prefer someone as principled as Sanders).
That's insane. She's one of the most progressive Senators, why should anyone waste their money and resources challenging her?
Seriously. This is the second or third-most progressive senator in the Senate. I'm willing to bet that without her/her policy team pushing Biden, we wouldn't have things like universal pre-K in the national conversation now.
