Of all the myths the Republicans have perpetrated, and there are a lot of them, perhaps none is more powerful or insidious than the foundational one that this is an overwhelmingly conservative country and that progressives are outliers in it, along with its pernicious corollary that conservatives are “real” Americans while liberals (and the minorities who support liberal policies) are somehow counterfeits.

It is a brilliant bit of propaganda. The only problem is that it isn’t factually true, at least for those who still believe in facts. While there are more self-described conservatives than liberals, in large part, I think, because of the conservatives’ success at conflating their brand with Americanism itself, the gap has been narrowing. And in any case, party identification is just about evenly divided between Democrats and Republicans. What is more important: Most Americans reject conservative policy positions. Again and again, on issue after issue, the majority of Americans seem to tilt to the left: on immigration, including Trump’s border wall; on Obamacare repeal; on leaving the Paris climate accord; and on gay marriage.

So why then do conservatives control all three branches of government? More to the point, why do they control Congress and the presidency when Democrats got more votes? You might conclude that America is being held hostage by a minority group of conservative zealots. And you would be right.

There is an old saw that politics is about numbers, and in a true democracy that would be the case. But ours is not a true democracy. Even after addressing the fact that nearly 90 million eligible voters do not vote, our system weights some votes more than others, and these weighted votes almost always work to the Republicans’ advantage, giving some 35 percent to 40 percent of the electorate a disproportionate share of power.

Here’s how it works:

1. Rural votes are worth more than urban votes.

For the first few months of his presidency, Donald Trump delighted in showing guests an electoral map of the country in which huge splotches from the South through the Midwest and into the far West were red, indicating Trump’s support. He was right, of course. Those were areas that voted for Trump. Except that those splotches were sparsely populated. The dark blue dots in urban America were the densely populated Democratic areas — areas with more votes.

In most nations, geographical advantages don’t mean much. In our system, however, geography plays an outsized role. It’s not how many votes; it’s where they are cast.

A lot of this, as we all know, is the result of gerrymandering — a point that New York Timescolumnist Michelle Goldberg made in her debut op-ed about the “tyranny of the minority.” If you want some sense of how badly gerrymandering hurts Democrats, consider this: In 2012, 224 congressional districts voted for Romney, 221 for Obama, though Obama easily won the overall popular vote by nearly 4 percent. This Republican reward has been referred to as a “seat bonus” — the degree to which Republicans get more seats than their popular vote would warrant. According to the Brookings Institution, Republicans received just under 50 percent of the congressional vote, but wound up with 55 percent of the seats. They also got bonuses in the 2012, 2014 and 2016 congressional elections — again, 5 percent more House seats in the last election than their overall vote count would have entitled them to.

But the worst gerrymandering isn’t just politics and it isn’t just in the House; it is constitutional and it is in the Senate, where of course, seats are apportioned by state. Since rural and sparsely populated states are far more likely to vote Republican, and since all states, regardless of population, get the same two Senate seats, the GOP gets a much larger bonus in the Senate than in the House. In the South, for instance, with a population of 103 million, Republicans are essentially awarded 22 seats automatically. (The only Democratic senators in the old Confederate states are Tim Kaine and Mark Warner of Virginia and Bill Nelson of Florida.) Meanwhile, four large Democratic states — California, New York, Illinois and Massachusetts, with an aggregate population of 80 million — get eight seats. This is minority rule, plain and simple.

I am not even going to get into the Electoral College, which operates on the absurd principle that it is not how many runs you score, but how many innings you win.

2. White votes are worth more than minority votes.

White voters are deeply advantaged not only because they still constitute a majority of the electorate, but also because (a) they can be gerrymandered into white-controlled districts while diluting minorities; and (b) because white majorities often work to increase their power at minorities’ expense. We see the latter most dramatically in voter suppression laws. A Washington Post study showed that these laws, designed expressly to reduce minority participation, have a tremendous impact:

By instituting strict voter-ID laws, states can alter the electorate and shift outcomes toward those on the right. Where these laws are enacted, the influence of Democrats and liberals wanes and the power of Republicans grows. Unsurprisingly, these strict ID laws are passed almost exclusively by Republican legislatures.”

The Post found that the laws widen the white advantage over blacks in turnout from 2.5 percent to 11.6 percent.

3. Rich and middle-class votes are worth more than poor votes.

Poor people, who are likely to vote Democratic, vote in far fewer numbers than the middle class and wealthy, who are likely to vote Republican. Only 47 percent of those earning under $20,000 a year voted in the 2012 election, while those earning $100,000 or more had an 80 percent turnout. (Meanwhile, only a quarter of the poor voted in the last midterm.) You can blame the voters themselves for apathy (Republicans would), and in a Cal Tech/MIT study of the 2008 election, some of these non-voters blamed their lack of participation on the choice of candidates presented to them. If anyone is entitled to be disenchanted with the political process, they are. But many others blamed practical obstacles that the system either imposes or does nothing to remedy: registration problems, transportation, illness, long lines, voter intimidation.

In short, the poor are often actively discouraged from voting.

Since 38 percent of American workers made less than $20,000 in 2014, this is a substantial chunk of voters lost — again, presumably Democratic voters, which is also to say that while we rightfully complain about economic inequality, we should also be complaining about electoral inequality that rises from economic inequality.

4. Old voters are worth more than young voters.

As with minority voters and poor voters, young voters, who skew Democratic, are less likely to vote than older voters, who skew Republican, thus reducing younger voters’ power. According to a Pew survey, the so-called Greatest Generation had 70 percent turnout in the last election, baby boomers 69 percent, Gen Xers 63 percent and millennials only 49 percent. (And this is not a function of youth; earlier generations had higher voting rates at similar ages.) Again, all sorts of reasons can be adduced, and according to one study, millennials, 55 percent of whom identified themselves as Democrats or Dem-leaning independents, are no less politically involved than their predecessors; they are just less electorally involved, preferring other forms of political engagement. While they cast 25 percent of the votes in the 2016 election, millennials make up just under a third of the voting-age population, which means their votes were worth less than those of the other cohorts.

Of course, you can blame them too for not voting, but Republicans make a point of making it more difficult for them to vote through many of the same mechanisms that affect minorities. To cite one egregious case, North Carolina Republicans petitioned the Supreme Court to reinstate the repeal of a law that allowed 16 and 17 year-olds to pre-register to vote, after the circuit court had ruled the repeal discriminated against those voters.

5. Single-issue voters are worth more than more general interest voters.
