2. The TPM TExt Has Been Corrected to Reflect that Obama's Lead "Remains" at 4%
I trust TPM as one of the better political sites and am willing to give them the benefit of the doubt that the writer made an error. There was another swing state poll recently that showed a larger lead. The text from PurplePoll doesn't reference what the March result was which I found frustrating. I do think your moran adjective is a bit harsh IMO. I think if you follow TPM regularly you no doubt would have seen this as an error and not some nefarious scheme to push a narrative or other agenda.
