No need to canvass on water charges

I have no problem with people protesting over the water charges.

That is their democratic right in this country. My question is: if the anti-water charges protesters are so confident of their stance why go house-to-house canvassing on the issue as is happening here in Galway?

I recently ran in the local elections. Myself and members of my team engaged in house to house canvassing as is normal. Why engage in canvassing on water charges in the first place?
