ARRINGTON: Mark Sanford and the career politicians cheated on us. We sent him to do a job, but he left his post and set off down a long trail towards obstructionism. I'm Katie Arrington and I approve this message. I'm a conservative businesswoman and I'm running for Congress to get things done, not to go on CNN to bash President Trump. I'll cut spending, strengthen our military and get rid of the career politicians. Bless his heart – but it's time for Mark Sanford to take a hike for real this time.
