Prompted by Media Matters, the Los Angeles Times posted this correction at Andrew Malcolm's blog:

FOR THE RECORD:
A Top of the Ticket post Tuesday on the relative popularity of Sarah Palin and Barack Obama erred in stating in the text and the headline that there was a Palin-Obama gap of 1 point. Two separate polls were cited, as the post notes, so the findings are not directly comparable.

Malcolm had used Palin's favorable rating and compared it to Obama's job approval rating, to make his false conclusion. It was the second time in three weeks that Malcolm had used the phony premise.
