I see many posts encouraging people to canvass, and I don't know how good advice this is.
We had two grassroots groups in NH (Operation Live Free and FACT). And they spent more than a month canvassing.
There was also the Christmas in NH effort, plus the other volunteers coordinated by the campaign.
I think that NH had much more canvassing than Iowa.
Yet we scored 2% more in Iowa than NH.
I've read some stories about people becoming increasingly annoyed by canvassing.
I know I hate when someone calls me, or even worse, knocks at my door to sell me something, or to try to convince me to join their cause (religion, charity, etc.).
I don't know how good canvassing is. But, what really intrigues me, is if in reality it is bad.
