If you say so. I'd caution though that if you think the rank and file membership who pound the streets talking to non members will do so for Corbyn, you're being similarly naive. This can be extended to thinking that the new members will fill that void.
New members are already filling that void and plenty of longer term members will be happy to join them, even some who support Smith but have more about them than your impressions suggest.
