Or, for that matter, a Republican.
She has registered as a Independent.
Of course, she will probably caucus with the Democrats in order to keep her committee assignments.
It would be interesting if she decided to caucus with theRepublicans, making the Senate 50/50 again.
But that’s not going to happen.
