Rep. Parker Griffith, an Alabama Democrat is switching to the GOP today.That is a huge blow to Barack Obama. Griffith was an extremely endangered Democrat.We should now hope him be an extremely endangered Republican in a primary. We will not fix the GOP's problems if we keep allowing people who are not one of us to suddenly switch the letter next to their name and magically become one of us.Being a Republican should be about more than just the letter next to a person's name. We can improve that seat.Here are Griffith's earmark requests. He voted for Pelosi for Speaker. He's actually been more regularly with Pelosi than Jim Marshall (D-GA). We can pick this guy off and get a real Republican in that seat.Again, changing the letter next to your name does not magically make you one of us.See the Club for Growth for more. They put it into perspective.
