A lot of people don't pay any attention to proposals. There's ~150 whales with a lot of HP and most of them don't vote for witnesses or pay attention to proposals. You can't automatically assume that because a proposal isn't voted that it's because support for it is low. Getting things voted on whether it be posts, proposals, or witnesses is generally about getting the word out. The proposal had a short build up, so my conclusions would be closer to not enough eyeballs than not enough support.
