guess what? mark sanford just gave what sure sounded like a concession tonight, giving us our first big headline from this primary night. that can only mean steve kornacki at the big board with more. that's a big bit of news right there. >> it is a very big bill of news. a couple surprises, a couple important things. let's start right there. the first district of south carolina on the coast. you see the magic number is is also a runoff state.use so not only was airington the challenger running ahead of sanford. the question was as these votes came in, was she going to get over 50% so this didn't get kicked into a runoff. it looks like just about all the vote counted here, accounted for. so think about this.
