After spending the debates in the under-card group, Sen. Lindsey Graham of South Carolina has decided to throw in the towel. Polling at 0.5%, the Graham campaign decided to make the announcement today -- the last day to remove a candidate’s name from the South Carolina primary ballot. Despite being well respected in the Senate and with strong under-card debate performances, Graham was not able to break into the prime-time pack. On a Monday conference call, he said: “One of the biggest problems we’ve had was to get our voice on equal footing with others.”
