Funny Thai no vote billboards

Seen today in Roi Et city:
Towards the upcoming election July the 3rd, the People's Alliance for Democracy PAD and the Heaven and Earth Party have joined forces in a campaign to promote casting blank votes. Both parties are against the politics of both current pm Abhisit and former pm Thaksin. A previous campaign in begin of June, where  animal heads were used as well, was ruled to be illegal. The official reason was that the billboards were too large and were displayed in an unproportionally high quantity.
Purely relying on Thai sources, the new slogan states: "Don't vote for an animal to become prime minister", but I'm not fully sure if this is correct. (Masters of Thai help me out here..)

Alltough all other parties seem to be represented in Roi Et city, billboards of Abhisit's Democratic Party are marked by absence. The bitter truth is; they wouldn't last very long.
On highways outside the city many billboards of Abhisit have been damaged, defaced and in some cases daubed with red paint. As in many countries this is an illegal act here as well, but so far law enforcement and replacing billboards have sorted little effect.
