Legal Insurrection will be offering a polls tutorial:

I'm pleased to announce that next week Legal Insurrection will have a special guest series of posts on pollling, written by Matthew Knee, a Ph.D. candidate at Yale (don't hold it against him) specializing in campaigns and elections, ethnic voting patterns, public opinion, and quantitative and experimental approaches to political science.

The posts will run starting Monday, and will focus on polling issues which arise in the political context, such as weighting of samples, framing and sequencing of questions, and other factors.
