This combination of 2018 photos shows N.C. Sen. Dan Bishop and Dan McCready. Bishop, best known as the architect of the state’s so-called bathroom bill is racking up contributions and endorsements as he runs in the repeat of a congressional race marred by a ballot fraud scandal. The state elections board unanimously ordered the new election after Mark Harris, the Republican in 2018’s race against Democrat Dan McCready, used a political operative accused of improperly collecting mail-in ballots.
