COAST TO COAST, BORDER TO BORDER, MAJORITY REPUBLICAN COUNTIES. The Cranky Professor has located USA Today's county-by-county plurality map. Look at Massachusetts, Nebraska, Kansas, and Oklahoma. Those are the only three states in which any Congressional district in the state will select an elector for the state winner. Elsewhere, under a rule that allocates electors by congressional district, (Maine an exception in reality; the map shows unallocated counties) there is a possibility of split allocations. The reasons for Colorado considering a proposal to go to allocation by district seem clear from the breakout on the map.
