Don't know the reason of your doing that. It would be a major task for each poll - clone your template, change the template, update the template, then change the template back, update your template again. I am not sure if you want to do that. But why not showing results?
[edit]
template file
modules/xoopspoll/templates/blocks/xoopspoll_block_poll.html
at the end of the file, remove
<tr>
<td class="foot" align="center" colspan="2"><input type="submit" value="<{$block.lang_vote}>" /> <input type="button" value="<{$block.lang_results}>" onclick="location='<{$xoops_url}>/modules/xoopspoll/pollresults.php?poll_id=<{$poll.id}>'" /></td>
</tr>
then add it back
* Edit - changed the above to use the [ code ] block rather than a quote one
