Sorry for the issue you are experiencing...
Can you tell me what browser you are using? Do have ad blockers or any browser add on that you think may affect the voting system? Are you allowing cookies?
I've checked using Chrome Version 25.0.1364.152 m, FF19, IE 9.0.8.. and they all display the poll just fine.
Please let me know so I can investigate and I do apologize for inconvenience.
