Analysis: A high-altitude way of looking at America's political divide and what it means for Dems.


When protesters swarmed major airports like Dallas-Fort Worth, JFK and San Francisco International in January 2017 to decry President Donald Trump's ban on travel from predominantly Muslim countries, it presaged the contentiousness that has come to define his first term.

But it also highlighted an emerging electoral trend: The growing chasm between highly multi-cultural metro areas with direct links to other continents, and the rest of the country that lacks such connections.

America's political divideis often characterized as urban vs. rural. But truly rural areas are a relatively small slice of the electorate: In 2016, only 14 percent of all voters cast ballots in counties defined by the Census Bureau as non-metropolitan.

Instead, the most significant divide in 2020 could be between the large, diverse metro areas that make up the majority of the vote on America's coasts, and the smaller, less diverse metro areas that are not as likely to have reaped the benefits of a globalized economy.

And Democrats' ability to defeat Trump in the Electoral College depends on whether they can hold their ground in the metro areas served by airports that don't have a lot of international flights — but had a runway long enough to land Trump's Boeing 757 for a rally in 2016.

An analysis of flight schedules for U.S. primarily commercial airports, Census data and election results yields a stark portrait of Democrats' challenge in 2020. Let's divide the country's electorate into four geographic tiers:


Global Metros

Roughly 41 percent of the country's electorate resides in large metropolitan statistical areas served by airports with at least two regularly scheduled flights to destinations outside North America. Examples include Los Angeles, New York, Chicago, Dallas, Atlanta, Miami, Minneapolis and Seattle.

International Metros

Another 14 percent of the country's electorate resides in metropolitan areas served by airports with at least one regularly scheduled international flight but fewer than two transcontinental flights. Examples include Indianapolis, New Orleans, Nashville, Kansas City, Pittsburgh, Columbus, Raleigh and San Antonio.

Regional Metros

Another 31 percent of the country's electorate resides in metro areas served by airports featuring service from at least one of America's four largest domestic carriers — American, Delta, United or Southwest — but no international flights. Examples include Des Moines, Flint, Toledo, Buffalo, Pueblo, Erie, Little Rock and Spokane.

Non-metro areas

Lastly, 14 percent of the country's electorate resides in counties defined as non-metropolitan by the Census Bureau. These rural areas make up the majority of the population in states like the Dakotas, Vermont and West Virginia, but they comprise a much smaller share of the population in most larger states.

The good news for Democrats? Trump is downright toxic in "Global Metros," the largest component of the electorate.


In 2016, Hillary Clinton took 62 percent of all major-party votes cast in these mega-cities and their suburbs, exceeding Barack Obama's shares in 2008 and 2012, as well as her husband's showings in 1992 and 1996. These urban/suburban melting pots are where Trump's rhetoric about immigrants and exhortations for non-white congresswomen to "go back" to other countries backfire. Of the 43 House districts Democrats wrested from GOP control in 2018, 28 were wholly or partially located in these metro areas.

Additionally, Democrats are holding their ground in "International Metros." In 2016, Hillary Clinton took 53 percent in these second-tier metropolises, roughly the same share Obama took in 2012 and Bill Clinton won in 1992.

The bad news for Democrats? They are backsliding in "Regional Metros" — the smaller cities and suburbs where residents would have to connect through a larger hub airport to travel internationally, and where Trump's hard line on immigration and protectionism is likelier to resonate. In 2016, Trump took 55 percent of the vote in these metros, up from Mitt Romney's 53 percent in 2012 and John McCain's 51 percent in 2008. And Trump clobbered Clinton in non-metro counties, taking 67 percent, up from Romney's 60 percent.

But the even bigger problem for Democrats: the "Global Metros" where Trump's unpopularity continues to deepen are disproportionately concentrated in states that aren't poised to be decisive in the Electoral College in 2020.


For example, even though residents of "Global Metros" make up 41 percent of the vote nationally, they make up 76 percent of the vote in California, 66 percent in Illinois, 97 percent in Maryland, 64 percent in Massachusetts, 89 percent in New Jersey and 61 percent in New York — all states that Democrats win comfortably anyway. They're also 50 percent of the vote in Texas, a state where Democrats are on the rise but Trump still won by nine points in 2016.

But residents of the "Global Metros" are just 44 percent of the vote in Michigan, 34 percent of the vote in North Carolina, 34 percent in Pennsylvania, and five percent in Wisconsin — all states that could be near the tipping point of the Electoral College.

Meanwhile, "Regional Metros" and non-metro areas — the places where Trump achieved liftoff in 2016 — are just 45 percent of the electorate nationally, but they're significantly over-represented in the most critical battlegrounds: They make up 56 percent of the vote in Michigan, 59 percent in North Carolina, 46 percent in Pennsylvania and 68 percent in Wisconsin.

Of the five states the Cook Political Report rates as 2020 toss-ups, Arizona is the only state where residents of "Global Metros" make up a majority, 66 percent — a statistic inflated by the fact Phoenix's Maricopa County is home to a majority of the state's population.

Democrats have declined most sharply in rural America, but it's "Regional Metros" that should concern the party most in 2020.

Not only do these smaller cities and suburbs make up an outsize share of the vote in key states — compared with both rural and "Global Metro" areas — but Democrats still have plenty of room to fall from Clinton's 45 percent share in 2016. If Democrats can maintain altitude in the "Regional Metros," their gains since 2016 in "Global Metros" should be enough to overtake Trump and reoccupy Air Force One. If they can't, Trump could very well win re-election while losing the popular voteagain.

For now, Democratic presidential primary candidates are drawing enthusiastic crowds to rallies in places like New York, Seattle, Austin and San Francisco. But to beat Trump, Democrats will need to ask themselves which candidates' proposals will fly in Erie, Saginaw and Green Bay.

Methodology: This analysis reviewed major airline flight schedules, FAA data on primary commercial airports and Census definitions of Metropolitan Statistical Areas (MSAs). Metro areas without a primary commercial airports were categorized based on the nearest primary commercial airport. For example, the Ann Arbor, Michigan metro area is served by Detroit, Michigan's airport and categorized as "global." In addition, all vote shares reflect percentages of the two-party vote only.
