get node creation date in a view
Poll is a core module and it appears that it doesn't make the "end date" available to views. You could add your own "end date" field to the poll content type but then you have to enter it twice.

Or try the more advanced pollfield module:

Because pollfield allows you to build polls as part of the CCK system, this module provides a more flexible polling option than the Drupal core poll module.


Please let me know how it goes, I'm interested in the pollfield module myself, just don't have time right now to play with it ;-)
