Volunteers gathered to make get-out-the-vote phone calls from President Barack Obama's campaign office in Mountain View Tuesday night. Once polls closed in swing states, they stayed to watch election results, at first anxiously and then with mounting excitement and relief. Major news networks announced around 8:15 p.m. that Obama was projected to win the presidential race against former Gov. Mitt Romney. The swing state of Ohio, where both candidates had stumped tirelessly, proved to be the deciding factor in calling the race.
