force users to reply to a poll thread before voting

[influence]

I think this should be simple.

Is there anyway I can change the default poll system so that before a user attempt to vote on a poll, there should be a message saying "you must reply to this thread before replying" or if they attempt to click and vote on that particular vote, a error message should show up saying "You must reply to this thread before voting on this poll"

This seems like something simple and I hope someone can help me accomplish this modification.

thanks
