Hugh Pickens writes "Michael Scherer writes that the Obama fundraising machine has deployed a new cellular campaign weapon designed 'to trigger the campaign finance equivalent of an impulse buy' during key political moments in the campaign. The tool links two familiar technologies, SMS and one-click purchasing, by sending out an SMS message to cell phones and smart phones of tens of thousands of previous campaign donors giving them a one-click option to give more money. 'Campaign officials hope to be able to return to donors in key moments of emotional excitement,' writes Scherer. One person familiar with the ask says that the response rate has been more than 20 times greater than any text message solicitation Obama has sent out before and and the reason is simple: Even with an iPhone, it remains an arduous hassle to enter all the information that is typically required to buy anything online with a credit card. The trick is that anyone who gives even a few dollars to the Obama campaign is asked if they want to keep their credit cards on file to participate in what the campaign calls 'Quick Donate.' Now donors just need to write '25,' or '10,' and that amount of dollars is immediately drawn from their credit cards. One of the Obama campaign's best fundraising days in 2008, for instance, came right after Sarah Palin's convention speech. Now partisans can 'vent their outrage or enthusiasm by simply typing one number into their phone.'"
