I call bullshit. Most of the people who identify themselves as Democrats will vote for whoever is running on the Democratic ticket. Most of the people who identify themselves as Republicans will vote for the Republican candidate. The only time you're voting for 'individuals' is when you're voting in a primary where you have more then one candidate from the same party to pick from, and even then, in a lot of cases, it's a choice between clones. "Do I vote for the white guy who is spouting the party line, or do I vote for the other white guy who is spouting the same party line?"
The only people who don't fall into that are people who consider themselves independents, and a lot of the time, they're stuck with a bad choice or a worse choice. (And even then, if the candidate they like is from a party that isn't demographically favored in their area, their choice means fuck all.)
Yes, that's pessimistic. But saying that the U.S. is different because we vote 'for individuals' is disingenuous at best.
