Carr, a Murfreesboro business consultant, told WTN-FM host Ralph Bristol that he decided to abandon his challenge to embattled U.S. Rep. Scott DesJarlais to instead take on Alexander because he considers the senator "the most liberal member of the delegation from Tennessee." (link)
Just now hearing this, I will have to let it sink in.
This is certainly good news for Jim Tracy. Jim Tracy was ahead in fund raising and appeared to be destined to beat Carr in the three-way primary between DesJarlais, Tracy and Carr. Tracy should now win that primary handily.
I have serious reservations about Joe Carr. The main thing that concerns me is that he was the sponsor of a bill in the state legislature that would have made it a crime to enforce any new federal gun laws in Tennessee. If his bill would have passed, local law enforcement agents would have been required to arrest Federal agents enforcing Federal gun laws in the state. Imagine Barney arresting Marshall Dillon. Someone could die. If the Federal Government violates the Second Amendment, the proper course of action is to challenge it in the courts, not start a rebellion. The supremacy clause is as much as part of the Constitution as the tenth amendment.
While Joe Carr is the most qualified of any of the other potential candidates mentioned as possible challengers to Alexander, I don't think he can take the nomination away from Alexander.
