Poll.module allows you to run simple multiple choice polls on your site. After creating the necessary categories, you can add a poll through this administration interface.
The poll.module also has a block to show the latest poll. If you combine it with a poll category that doesn't promote to the mainpage, you'll get a side-block only poll system.
If you want to set a limit on the duration of a poll, use the Poll Duration setting. After the specified interval, the poll will automatically be closed, preventing anymore voting.
