I'm not convinced she's a changed person yet. It could be that she's starting to reconsider, or, more likely, that she's thinking ahead to supporting things that will enable Republicans to stay in power (at least she's saying that this would be by producing results for average Americans, so there's that).
While she'll probably never be somebody I'd vote for, it would be nice to have people in Congress who are decent people I just happen to disagree with.
It'll take time and results before I'm convinced.
