With his rise in popularity Donald Trump has now started to have to defend himself against Republicans who think that his focus on the birther issue is going to hurt the party. This includes Karl Rove, who recently called Trump a "joke candidate." Now you can add former RNC chairman Michael Steele, who appeared on Hardball last night and dismissed the birther issue as "silly," to that list. "Rank and file Republicans don't give a rat's giblet let about the birther issue."
