What is "virtue signaling" in this case? Proposing and advocating for progressive legislation? Refusing to vote on controversial policies that are endorsed by the party? Using her bully pulpit to try and push issues?
Voting no on the debt ceiling bill was not very "neoliberal". But I guess that "doesn't count" since it passed anyway?
Seems to me that "virtue signaling" is just a disingenuous way to discredit someone doing the job of being an elected legislator. Don't vote for her if you don't like her, but try to have an actual specific reason for it.
