Nothing wrong with that sign. Monks is an official write in candidate. The slogan, "Its your choice not the governors" is a good one. It is a Dim govenor and you are not getting a GOP DA from him
All of that said, Durham would be better served by an honest Dim rather than Nifong. And Monk can only serve to split the vote. So I prefer him not do this. But it is hardly a dirty campaign trick.

Monks has every right to run a campaign, but the prick knows full well he's sticking it to the lax players. He's earning his moniker "Nifong's Little Helper".
