Andes taggers don't like Marty

We got a tip last night that a very meticulous graffiti artist has vandalized the sidewalk on the edge of the village of Andes along Rte. 28, right next to the Andes Town Hall. When we went to take a look for ourselves, we found not one but three carefully stencilled tags declaring the author's sphincter-oriented opinion of someone called Marty. More legible photos below:

We hope it's just a coincidence that the name of the Town Supervisor of Andes is Martin Donnelly. Anyone have a guess as to what's motivating this mystery vandal?
