From a Charlotte Observer article about the attendence (or lack there of) for North Carolina's federal delegation:
Rep. Robin Hayes, a Concord Republican, missed 59 votes, tied with GOP Rep. Howard Coble of Greensboro, for the second-largest number of missed votes in the delegation.
That's 59 of nearly 1,200 votes, or a miss rate of 4.8 percent or so.
