Calm down folks. Bristol Palin isn't going rogue. A poseur has set up a fake Twitter account under the name @Bristol_Palin and is pretending to be the "Dancing With the Stars" finalist. The imposter posted a phony and unkind tweet about her mom, former Alaska Gov. Sarah Palin, on Sunday, saying, "You are a paid member of the 'lame stream media' you're always referring to, mom. Fire all of your ghost writers and tweet for yourself :(" But the folks over at SarahPAC told Yeas & Nays on Monday evening that "This is fake and Bristol will likely issue a statement."
