SOMERSWORTH, N.H. –On the surface canvassing would appear to be a simple process. Walk up to a house, bang on the door, suck up whatever response you get, repeat.

But in New Hampshire it’s a science. Campaigns spend hours mulling over voter lists, creating maps, drawing diagrams, analyzing data. All to make sure the right doors are knocked on.

And the people tolerate it without much fanfare.

Saturday morning I found myself in Dover N.H., in a van with two state representatives, a Portland school board member and a lobbyist. I’m following this group of Mainers as they volunteer for John Edwards.
