Double voter is either SAL, scrilla (unlikely as he's claimed Miller), IMPULSE, Mike J Cab00se or Haystacks Calhoun. All of them bar Mike J has voted this day, so only Mike J being the double voter will mean it's not a hammer.
What should we be waiting for?
iMac has claimed cop. He's either insane or paranoid cop. He'll have results of interest, and as there's a day killer, if we hammer Kenny before iMac logs on, he (iMac) could die before getting a chance to share his results.
