This combines the old technique of lobbying of MPs by citizens with a practice more commonly used in the US, which is mobilising the public using the Internet. Canvas Your MP is a Liberal Democrat led campaign, the challenge for them now is making an impact. In the US lobbying strategists have developed complex equations for both moving the votes of senators and gathering participants and supporters. For them it is about click-thrus, they will pay to embed a link on popular sites, recognise that no more than 10% click, that of that 10% only 1% sign up and so from that work out how many banners are needed on which sites to get the right amount of visitors clicking. Not sure what the distribution method for this campaign will be, currently it is viral and passed from friend to friend via FriendFeed, Facebook and over email, but is this sufficient to get to enough MPs across the country, and get anywhere near a significant number of constituents contacting their MPs? Is the informal recommendation via the online community the best strategy, or does the strategy need ratcheting up a notch.
