I managed to figured it out even though this behavior still makes no sense to me. I had some additional recorded vocal takes (that wound up not being used in the song) that I had archived and also had them hidden from the track and console views.
I un-hid these archived tracks so that I could see them in the track and console views. At this point I was able move clips to anywhere that I wanted to.
I don't understand why X2 won't let me freely move clips to where I want to move them when there are archived/hidden tracks.....
