Hi
As Mentioned by Kendall "The Poll component would be an extension of Tally and would need to be re-implemented using SRP if/when you upgrade to AEM 6.1 Communities",
But there is another way to implement it, that is via Jquery Plugins.

// Integrating the JQuery Framework into Adobe CQ
So using the above article we can integrate AEM with Polling Jquery plugins.

I hope this way you can create a custom component to fulfill your purpose.
