I'm starting to lose hope because some of the big voters are unvoting those opposed to HF21.

drakos is going backwards because big voters like berniesanders have unapproved him. See

It would take thousands of small accounts voting to make up for that - and thousands arn't voting, it's more like 2 or 3 a day.

It's possible that lots of the small accounts simply don't know what is happening because they're in their little circles and don't follow technical steemit news.
