Wow, this is one of the worst time-lines I've ever read. Al Gore and John Kerry representing the Democratic left? Holy sh**t.
Well, it depends on how the political trend has run. After all, this is a hundred years into the future, and even in Gore and Kerry's time within this timeline, what would have been the center in American politics could be the Left, and by 2090, the Far-Left. At the same time, an opposite trend could occur. Within their our history, the Republican and Democratic parties have switched almost entirely in their ideology's.
