Have you read Drudge's latest post on this? Her family has released a statement saying they DO NOT agree with her political motivations. They support the troops and the president. It's signed by the grandparents, aunts uncles etc totally disagreeing with Sheehan. They slam her pretty badly in the statement.
Unless her family goes on TV and specifically lays out how nutty and irresponsible she is, it isn't going to matter. The moonbats can even deny it is legitimate. Plus the father would help too.
I heard this earlier. The family is distancing itself from her. What an embarassment for the family.
