libby won't be pushed out of the party, no matter who's leader. in the near impossible event that the ndp goes full new labour, even there we had examples of radical mps who were perfectly at home in the party - think george galloway before he went nuts with the saddam thing (and i don't think we'll see libby on state teevee in syria singing assad's praises). and that's IF mulcair takes the party to the "center", which he won't. people, the reason that these guys are kicking up this whole issue is that they want their campaigns to win. it's that simple. IF mulcair becomes leader, a year from now, i guarantee that we'll all be looking back on this realizing that it was all overblown.
and as for libby leaving caucus voluntarily to pursue an opportunity in bc, where would she run? seems the ndp there already has all the potentially libby-friendly seats locked down.
