This site doesn't normally track the lies of Keith Olbermann since there are so many and no one outside his bubble trusts anything he says. However, sometimes he crosses the line, as he did with tonight's "Olbermann on Palin: Socialist, fraud/Governor doesn't have a problem with Alaska's socialistic collectivism" (link) which contains this:

Who was the collectivist share-the-wealther, who was boasting to the reporter visiting from "The New Yorker Magazine," of having been able to send a check for $1,200 to every man, woman and child in the state since, quote "Alaska is sometimes described as America's socialist state, because of its collective ownership of resources?"

And, the blurb under the video at the page above says this:

In this case, Sarah Palin is accusing Barack Obama of advocating socialism when she literally used that word to describe the collective wealth sharing in her home state of Alaska.

However, the quote in question is actually from the New Yorker writer (Philip Gourevitch), not Palin (link). There's only one instance of socialis* at that page, and it's the writer saying it:

Alaska is sometimes described as America’s socialist state, because of its collective ownership of resources—an arrangement that allows permanent residents to collect a dividend on the state’s oil royalties. It has been Palin’s good fortune to govern the state at a time of record oil prices, which means record dividend checks: two thousand dollars for every Alaskan. And because high oil prices also mean staggering heating bills in such a cold place—and because it’s always good politics to give money to voters—Palin got the legislature this year to send an extra twelve hundred dollars to every Alaskan man, woman, and child.
