One of the barbed chants of the resisters is "we are the majority!" That is not an idle boast. As we all know (well, all of us who do not believe the fairy tale about millions of phantom illegal voters), Hillary Clinton beat Trump by 3 million votes in 2016. Year after year, in total ballots cast, Democratic candidates for the Senate and the House rack up far more votes than do Republicans. But, thanks to the way district lines are drawn and the tilt toward small states that is embedded in the Constitution, the Republican Party enjoys a structural advantage that negates those numbers. It does not help, either, that young people and minorities have a tendency to skip voting in nonpresidential elections. So, 2018 will have to break the pattern and beat the system.
