The last time John McCain rode the Straight Talk Express, people still used VCRs and the words "You" and "Tube" were not spoken together. Last week, when McCain barnstormed Iowa, even the national newspaper reporters had to file regular blog entries, and digital video cameras were plentiful. Here are two exchanges between McCain and reporters that I captured in the back of the bus. In the first, he admits that his presidential ambitions may be held captive by the fate of President Bush's surge plan. In the second, he claims to have never dressed in drag and dodges questions about homosexuality. This is just a taste of what's to come, as every moment of the presidential campaign becomes vulnerable to instant broadcast online.
