Her yes votes are meaningless as the judicial appointments would pass with or without her vote. Thus she is successfully sending the message that she is a "middle-of-the-roader" and "Reaches across the aisle" or whatever term you want to use.
In reality, when the Dems want her vote they will have it.
She is voting not based on how she feels, but based on a desire to get re-elected.
Please, please don't fall for it.
I don’t think people are under any illusions about how she’ll vote when Schumer needs her. It’s just pretty nice not having to hear about McCain or Flake taking shots at Trump on the fake news circuit only to vote the exact same way as her when we need them.
