I love this little item from The American Prospect blog. An excerpt:

THE DOWNSIDE OF THE STEVENS CONVICTION.Ted Stevens’ indictment may be a huge victory for Democrats, especially if it helps tip the race for Alaska’s Senate seat to Stevens’ challenger Mark Begich. But some — particularly some progressives and enviros — have a mixed reaction about Stevens’ impending doom. An initial glimpse of this came when Diane Benson, the Native Alaskan Democrat challenger for Alaska’s U.S. House seat (who lost in the August primary), said in a campaign press release in July that she was “greatly saddened” about Stevens’ indictments. The latest came when Colin Powell, who Adam pointed out as a closet liberal, surfaced at Stevens’ trial to testify as a character witness for him, and then three days later endorsed Barack Obama for U.S. president. . . .
For a long time Stevens denied anthropogenic causes of global warming, but he more recently has begun removing doubt about it also.
“We’ve got global climate change, and it’s coming about partly naturally and part of it may be, I believe, caused by the accumulation of the activities of man,” he told the St. Petersburg Times.
“[Stevens] told me and others that addressing global warming is like buying insurance,” Williams told me, “you can’t be 100 percent certain that it is humans that cause it, but it’s better to be on safe side due to the potential costs involved.”
