A poll is displayed as two table rows, one of answers and another form fields to select those answers.

Why it matters

This layout requires blind users to memorize each answer and count its column position before selecting an answer.

Possible solution

There is a "Display Mode" setting for polls which allows the axis to be flipped, showing one column, with each row containing the form field and associated answer. This should be the default, and the "Display horizontally" option should be removed.
