I assume the raw wikicode inside a poll tag pair is used as key to find the underlying poll data, no matter what this code evaluates to.

The first and last newline of a poll is trimmed, so for example it doesn't matter for the poll contents if you have the question in the same line as the opening tag or in the next line. But both versions will be different polls. If you add or remove the unneeded newline afterwards, this will create a new poll. This means the key for data access is taken from the code even before something as basic as stripping newlines could happen.
