Turkey Week: Preaching To The Blue Choir

Cook Political Report editor Dave Wasserman lays out a grim  a highly likely 2020 scenario, one where Donald Trump loses the popular vote by a whopping five million or more and still wins the electoral college easily.

The nation's two most populous states, California and Texas, are at the heart of Democrats' geography problem.

Both behemoths are growing more diverse at a much faster rate than the nation — owing to booming Asian and Latino populations — and are trending toward Democrats. Yet neither blue California nor red Texas would play a pivotal role in a close 2020 election, potentially rendering millions of additional Democratic votes useless.

Over the past four years for which census estimates are available, California's population of nonwhite voting-age citizens has exploded by 1,585,499, while its number of white voting-age citizens has declined by a net 162,715. The Golden State's GOP is in free fall: In May 2018, the state's Republican registrants fell to third place behind "no party preference" voters for the first time. In 2016, Clinton stretched Barack Obama's 2012 margin from 3 million to 4.2 million votes. But padding that margin by another 1.2 million votes wouldn't yield the 2020 Democratic nominee a single additional Electoral vote.

Over the same time period, Texas has added a net 1,188,514 nonwhite voting-age citizens and just 200,002 white voting-age citizens. Texas' economic boom has attracted a diverse, highly professional workforce to burgeoning urban centers of Dallas, Houston, Austin and San Antonio and shifted the state's politics leftward — especially as GOP votes have begun to "max out" in stagnant rural areas. In 2016, Clinton cut Obama's 2012 deficit from 1.2 million to just over 800,000. But again, even cutting Trump's margin by 800,000 wouldn't yield the 2020 Democratic nominee a single additional Electoral vote.

Democrats' potential inefficiencies aren't limited to California and Texas: The list of the nation's top 15 fastest-diversifying states also includes the sizable yet safely blue states of New York, New Jersey, Massachusetts, Maryland, Washington and Oregon.

Meanwhile, demographic transformation isn't nearly as rapid in the narrow band of states that are best-positioned to decide the Electoral College — a factor that seriously aids Trump.

In 2016, Trump's victory hinged on three Great Lakes states he won by less than a point: Michigan (0.2 percent), Pennsylvania (0.7 percent) and Wisconsin (0.8 percent). All three of these aging, relatively white states have some of the nation's highest shares of white voters without college degrees — a group trending away from Democrats over the long term. And the nonwhite share of the eligible electorate in each of the three has increased at only a quarter to a half of the rate it has surged in California, Texas and Nevada.

Democrats eagerly point out that they swept Senate and governors' races in Michigan, Pennsylvania and Wisconsin in 2018. And they flipped two seats in Michigan and four in Pennsylvania on their way to taking back the House.

But Trump could lose Michigan and Pennsylvania and still win the Electoral College, so long as he carries every other place he won in 2016. And Wisconsin didn't provide as clear a verdict in 2018. Even with favorable turnout in a "blue wave," Democrats won Wisconsin's governor's race only by a point and failed to gain a House seat. If enough Trump voters who sat out 2018 — particularly white working-class men — return to the polls in 2020, the Badger State could easily stay red.

There are a lot of scenarios that could happen in 2020, but the most likely ones keep coming back to Wisconsin as the sole state that decides the presidency.  Running up the score in California and Texas isn't going to help Dems one bit when it comes to beating Trump.

And if Trump holds Florida and NC, he can lose PA and MI and still win if he keeps Wisconsin and Arizona, and should a 269-269 split occur -- again, not impossible -- the GOP wins because they have more state House delegations.

However, we can trade Arizona for Wisconsin.

Like I said, lot of scenarios.
