I think if the Clinton faction supports the Arabs and not Israel which I expect, then Lieberman is going to have to consider what is in the best interest of Israel and that would be joining Republicans for caucus purposes.
I agree with that premise. I don't have a lot of faith in Lieberman though. I had a certain degree of trust in the guy until he teamed up with Gore, and then watched as Gore melted down saying all sorts of terrible things, without so much as a whimper in response.
It would be good if we could come to some kind of arrangement.
