How call a block named Poll Recent from template?
In D7, you will need:

$block = module_invoke('module_name', 'block_view', 'block_delta');
print render($block['content']);


In the case of recent poll:

&lt;?php
  $block = module_invoke('poll', 'block_view', 'recent'); 
  print render($block['content']); 
?&gt;


Curiously, although defined in poll_block_info the delta is actually ignored in poll_block_view, perhaps as the poll module only provides a single block.
