How do I add opinion polls?

So does anyone know how I can add a question with radio buttons on my site to get public opinion. My first question would be what do you seriously think about Hillary Clinton?

Does she even have a chance? The second would have to be about global warming. I mean who actually belives this stuff?

I'm sure that you already know Sheryl Crow wants to limit the amount of toilet paper you can use to help WIPE OUT global warming. She wants to use"only one square per restroom visit, except, of course, on those pesky occasions where two to three could be required". (drudgereport.com)
