Compared to the way I have voted in the past, I don't think that not voting is unusual for me especially when I have no clue which one to vote for. In other games, I can abstain, but this one. . .
When I made that statement, I believe I also said that I probably wouldn't be back again until after the DP. I didn't want to pick the wrong one and come back to find that I picked the wrong one and be the one to push it over if the mayor isn't alive/hasn't solved. Besides, I'd feel scummy voting for someone to "hear what they have to say" and not coming back to listen/read before the day ends.
