Because dishonorable John McCain has apparently decided to run a campaign of lies.
A McCain-Palin ad has FactCheck.org calling Obama's attacks on Palin "absolutely 0" and "misleading." That's what we said, but it wasn't about Obama.
Our article criticized anonymous e-mail 0hoods and bogus claims about Palin posted around the Internet. We have no evidence that any of the claims we found to be 0 came from the Obama campaign.
The McCain-Palin ad also twists a quote from a Wall Street Journal columnist. He said the Obama camp had sent a team to Alaska to "dig into her record and background." The ad quotes the WSJ as saying the team was sent to "dig dirt."
Update, Sept. 10: Furthermore, the Obama campaign insists that no researchers have been sent to Alaska and that the Journal owes them a correction.
