I think it's hard to look at the guy and ignore all the mistakes, but it's also hard to look at him and ignore his accomplishments and things he took a stand for that were positive (or, more truthfully, fall in line with what my own political ideals are). Because he was in office so long, he has a much more complex legacy than most other politicians.
I just saw that he died and thought it was appropriate for the news and politics forum, considering his tenure in Congress.
