On the one hand, I would prefer if posters actually show some love to their questions. That means (none of these are specifically directed at the OP per se, but more of general observations) that question askers should, ideally, engage the community when they leave comments asking for clarifications, and be prompt about revising the question when, for whatever reasons, the community decides that it is not up to the usual standards. This in particular means that I would prefer users not to ask a question the day before a planned three-week vacation. I think of this as an issue of being polite: if one wants to ask something of the community, one should expect to be on hand to clarify the request.
On the other hand, now that the situation has already arisen, here are some reasons why it is better to re-open the new version instead of trying to revive the old deleted one.
First and foremost, please remember that the automatically deletion is made by a bot following a very precise set of directions. For closed questions, even if you asked the moderator to undelete the question, we would be fighting against a script that is run weekly. If the OP cannot get the question in good shape to re-open (by that I mean convince five community members to re-open it) within the week, it will go * poof * and be deleted again.
Secondly, in this particular situation, the problem is compounded by the fact that the original deleted question carries also some downvotes. So just re-opening is not enough to guarantee the survival of the question in the next round of clean-ups.
Thirdly, and more generally, I can imagine circumstances where a question asker formulated a poor question at some point in time, and wasn't able to edit it to be better (for whatever reason). But some time later, the same question asker may have figured out how to ask the same question, but better. In view of the two points above, I feel that it is certainly more expedient for the asker to just ask the question anew rather than to engage in a possibly Sisyphean battle against the software.
