About the template for poll recent block in drupal 7 I need a template for the poll recent block in drupal 7.  I have tried with block--poll.tpl.php and block--poll--recent.tpl.php and poll--recent--block.tpl.php and I can't see any changes.  What's my wrong?
block--poll--recent.tpl.php will work if you clear your system cache (configuration > development > performance > clear all caches).

Worked for me.
