good question

If...

You don't know how to use the internet, you don't know that Czechoslovakia is no longer a country, you don't know Sunni from Shia, you don’t know much about the economy, you're uninformed about women's health issues, you don't know whether you're for or against gay adoption, stem cell research or setting a timetable for withdrawal from Iraq, you don't know what countries share a border with Pakistan, you don't know when the surge began, you no longer object to waterboarding or closing Guantanamo, you don't tell the truth about your votes on veterans issues, you said Putin was the leader of Germany, you think alternative energy means switching from regular to premium, you say you know how to win wars but you haven't actually won any, your idea of a funny joke is suggesting different ways to kill people in other countries, you want to keep giving tax breaks to the wealthy but not the middle and lower class, you confuse Somalia with Sudan, you thought voting for the Iraq war was an exercise in good judgment, you once said "I disagree with what the majority of Americans want," you think Social Security is "a disgrace," your idea of health care is apparently 'take more vitamins,' you voted to support Bush's policies 95 percent of the time last year and 100 percent of the time this year, and over the course of a single week you unfairly attacked both your opponent's patriotism and his humanity...

Then tell me again, Senator McCain: why should Americans vote for you?
