Congressional district voting casts an electoral vote for any candidate winning a state’s congressional district. Two more electoral votes are cast for the state to represent its two senator seats for the candidate who wins the most votes within the state. Example: Nebraska casts three electoral votes for its three congressional districts and two electoral votes for the two senators, to provide a total of five electoral votes.
Congressional districts within many states are often drawn to give a reigning party an advantage (referred to as gerrymandering). Using this approach unfairly gives political parties an advantage in those districts. Today, the advantage would be clearly for the Republicans because they are dominant in more districts than are the Democrats.
Congressional district voting also uses the all-or-nothing approach for each district and causes many votes to be suppressed. The two electoral votes cast within the state are also cast on an all-or-nothing approach, further suppressing the voting sentiment.
Notice, too, that each vote is essentially counted twice: once for the congressional count and another for the state count. Congressional district voting, then, subjects votes to be suppressed twice in any presidential election.
