Edward Luce writes: Republicans are paralysed on two counts. First, the party cannot disown what Mr Trump is doing without repudiating themselves. His victory was the logical outcome of the party’s “southern strategy”, which dates from the late 1960s. The goal has been to siphon off southern whites from the Democratic party. Most Republicans have preferred to keep their tactics genteel. The signal of choice has been the dog whistle rather than the megaphone. Thus, in one form or another, most Republican states are reforming their voter registration systems. The fact that such laws disproportionately shrink the non-white electorate is an accidental byproduct of a colour-blind crackdown. Even without proof of widespread fraud, voter suppression has plausible deniability. Over the years, the same has applied to various wars on crime, drugs and welfare fraud, which were never discriminatory by design. Mr Trump has simply taken that approach into the open.
