According to the Swing State Project (via PPP), in the last election only 23 Republican members of the House did worse than John McCain within their own districts. Two of those 23 were Virginia Foxx (NC-5) and Patrick McHenry (NC-10). McHenry's performance relative to the party's presidential nominee was the sixth worst of any member of the GOP caucus.
Tom Jensen at PPP has remarked before that these statistics suggest just how strong Roy Carter and Daniel Johnson were as challengers to Foxx and McHenry, even though they lost. Jensen also opines that the NC-5 and NC-10 are "completely unwinnable" for Dems, based on the "current configuration" of those districts.
