The totalvotes column exists in the dbtable 'e2poll' and in the dbtable 'node', which means that only one is really getting used properly. This should either be renamed, or deleted, depending on what is appropriate.
Polls should probably use their own tables exclusively. Poll votes have already been removed from the vote table. I'd say remove poll-related values from node (only 32 of 258 polls even have a value in node.totalvotes) and rename e2poll.totalvotes. Or delete if you'd rather count(*) from pollvote.choice
Yeah, I'm going to be wiping out the e2poll.totalvotes column. I'm just avoiding doing any major schema work until we have a good database migration framework.
