I think the more interesting question here is: How does this impact 2008? Does Barack Obama still become the Democratic nominee that year, or does the legacy of Jackson's (presumed) massive loss scare voters away from him?
EDIT: IMHO, he might be a good choice for VP, but I personally wonder if the similarities are..."too much" (so to speak) for white America. Jesse Jackson was fairly "radical" by many folks' standards, and Obama doesn't even really come close to the "Jackson-wing" of the party. But in 2008, he was portrayed as a literal Communist/Islamic Extremist/Antichrist by the right, and a lot of people bought into it. So with a fresh wound from 2008, unfortunately, another African-American man who was at all "progressive" (I think) would be eaten alive. And, being a first-term Senator, may not seem "establishment" enough by their standards. It might (or might not) work out well for Hillary, though. But I might be too cynical about white America, so I wonder what others think.
