Where it will really get interesting is if a couple Republicans defect, these three democrats votes didn't "matter" with Gorsuch because he would have been confirmed without their votes, so they could appeal to their red state voters with no consequences. However, if their vote will actually be the difference between confirming or rejecting the nominee you are going to see the democrat party putting pressure on them like never before.
Funny thing is, like this story suggest it my be a pyrrhic victory. The democrats force these Senators to vote against the nominee, the nominee is rejected. Then all three lose their seats to Republicans in November, Trump renominates the candidate after the new Senate is sworn in and then Republicans confirm the nominee with no democrat votes needed. Then democrats get nothing other than a delay of a few months in the seating of the Justice and lose several seats in the senate for at least the next two years to boot.
That would be the only outcome that would increase my all consuming sadness over my current bereaved state.
