I think, and don't take this wrong, that what happened does show the power of one individual, but likewise it also show the power of the people. You lost one vote, yet all the other voters you have kept you back with in reach of the top 20 again. That is good news. When you make it back in the top 20, then everyone will be able to see that yes, We Can make a difference in the witness levels. That the people can take their vote and vote on and show support for one person and help them into the top 20.
Imagine if the people that mirror that one vote, if they did not have you as a witness, were to remove their vote from another pumpkin supported witness and give it to you, then they could make a difference with their vote.
Good luck and here is to a speedy climb back to the top 20.
