 By a few weeks prior to making his announcement on "Letterman", McCain was already beginning to trail behind former Mayor of New York City Rudy Giuliani in the polls, a situation attributed to his steadfast support for the Iraq War troop surge of 2007.In March 2007, with considerable press attention and in hopes of reigniting his efforts, McCain brought back the "Straight Talk Express" campaign bus that he had used to much positive effect in his outsider run in 2000.Like many candidates, McCain took to the internet in order to help boost his campaign; appealing to younger audiences by creating Facebook and MySpace pages, along with an account on YouTube.
