Though he’s announcing his VP pick on an app, Politico isn’t so sure. Romney’s rarely spotting using technology and is thus at risk of losing the votes of fanboys whose devotion to Apple is so great that it determines their presidential picks. “I don’t think Romney is a member of the thumb tribe,” said Paul Saffo, a Silicon Valley tech forecaster. “I don’t see him playing Angry Birds or losing an app among his many apps.” Perhaps Americans would feel better if he started updating his blog with passages from that journal he’s keeping on his iPad.
