How do you decide how to vote?

After tonight's shocker, and remembering astonishing results in the past, I realize that I may have very different criteria for who should win "American Idol" than the majority of voters. So I asked three separate pick questions, for the primary, secondary and tertiary factors you consider when you vote for a contestant. If there was a way to create a pick that let you choose multiple answers, I'd do it. But as we can't, I made three separate ones. They're here:

Choose your main criterion
Choose your second criterion
Choose your third criterion

When answering these questions, please make sure to choose different picks for each. Thanks!
