The Siegelman case smacks of a huge conflict of interest. The prosecutor's husband worked for the opponent's election campaign, for goodness' sake!
And to the poster who said nobody doubts he was guilty, you are plain wrong. The first case was thrown out by the judge, who said it was lame. The second, more serious case is controversial because a donation to a state is not necessarily a bribe, unless it is proven that the official personally benefited from it. Otherwise, it's just a political contribution and that happens all the damn time. Finally, when you have 52 former attorneys general (who know a lot more about the law than you do) including the Republican one from Arizona all saying that this was a miscarriage of justice, likely it was a miscarriage of justice.
Karl Rove and his dirty divisive politics has harmed America as a whole, and has ruined specific lives like that of Siegelman. Fixing the system and trying to subvert representative democracy, as Karl Rove has done, is nothing short of treason in my book.
Comparing this case to a sexual misdeed in the Clinton administration is a red herring. There were a lot of presidents who had their trysts, but they weren't aired due to gentleman's agreements with the press - including JFK and LBJ, among others.
