The Crosstab Weekly Newsletter
Welcome! I’m G. Elliott Morris, data journalist for The Economist and blogger of polls, elections, and political science. Happy Sunday! Here’s my weekly newsletter with links to what I’ve been reading and writing that puts the news in context with public opinion polls, political science, other data (some “big,” some small) and looks briefly at the week ahead. Let’s jump right in! Feedback? Drop me a line or just respond to this email. 

This newsletter is made possible by supporters on Patreon. A special thanks to those who pledge the top two tiers is written in the endnotes. If you enjoy my personal newsletter and want it to continue, consider supporting it on Patreon for just $2.

A Quick Programming Note:
Please consider this an apology for missing last week’s newsletter. I’ve compiled all the links I planned on sharing in this letter alongside the material from this week and expanded upon my usual This Week’s Big Question such that it’s about the length of a normal article. Thanks!
This Week's Big Question
Is Trump Vulnerable to a Primary Challenger?
It depends.

On last week’s episode of NBC’s “Meet the Press,” Chuck Todd previewed some polling numbers that showed young and old, college and non-college educated Democratic voters split in who they’re looking for for a presidential candidate. While I talked briefly about Democratic disunity in my weekly blog post about data in politics last Friday — and while I opined that the focus on a divide among Democrats was misplaced when, the day before, Republican Senators voted against the President in a funding bill to re-open the government — I wanted to dive today into the actual cleavages in the Republican Party. Is there a real shot that Donald Trump faces a primary challenger in 2020?
There are a few big moving parts here. Primarily, we have to decipher (A) whether there is support for a challenge president within the GOP primary electorate and (B) whether the Republican National Committee would be open to hosting such a challenger in contests, debates, etc. Given that the RNC pledged their “undivided support” to President Trump last week — and more importantly, given that state leaders have even gone so far as to suggest they might cancel their caucuses and primaries — it’s worth more to focus on (A) than (B). Since there is a wide availability of public opinion polling, quantifying support for a challenger to POTUS is also a much easier question to answer than whether or not the institutions of the RNC would be flexible enough to foster an anti-Trump candidate. So let’s look at the polling data.
According to The Economist’s most recent polling from YouGov, 85% of Republicans approve of the job that Trump is doing as president. From issues of the economy, to immigration, health care to taxes, GOP voters approve of his job performance. But maybe approval is just high among voters who admit they’re Republicans to pollsters. Maybe the real number is higher. For various reasons — including a study from political scientists Pablo Montagnes, Zachary Peskowitz, and Joshua McCrain recently published in the Journal of Politics — we might expect Trump’s real approval among the total pool of Republicans to be much smaller. In other words, his support among the caucus could be inflated in popular measurements and better measured by more specific questions. Indeed, by other measurements, there is a lot of resistance to the president among the GOP primary electorate.
According to the most recent ABC/Washington Post poll, 32% of Republicans and Independents who lean Republican say the primary electorate should nominate someone other than Trump. Illustrating the issues this might pose in the general election, only 70% of Republicans say they would “definitely” vote for him in the general election in 2020. So there’s clearly room for another candidate, but their chances begin (much) lower than 1-in-4, maybe even 1-in-10. So what would that candidate look like?
According to the data from the 2018 VOTER survey from the Democracy Fund’s Voter Study Group, the 2016 Republican primary was decided largely along the lines of opposition to elites, feelings toward Muslims and minorities, and attitudes about same-sex marriage and abortion. In the following, you can see how most voters who opted for someone other than Trump were “socially” liberal. It’s likely that a 2020 challenger would have to emerge from the same two quadrants of the graph. But would they find success? At least according to this plot, there aren’t very many Republican primary voters occupying socially liberal space.
Though it’s even further unclear who the candidate would be, the bigger issue is probably the size of the pool of voters. The (unweighted) VSG data puts the number of 2016 GOP primary voters who are also socially liberal at about 1-in-10. That’s not nearly enough to contest a primary, let alone win one.
Instead of making issue-based ideological arguments, A Republican primary challenge to Trump would likely have to bill themself as a superior candidate along electability and institutional grounds, or say they’re a “real” Republican. The #NeverTrump movement has largely been opposed to POTUS for his anti-democratic (small-“d”) values, such as rhetoric that characterizes the press as the “enemies of the people.” Perhaps among Washington elites, a challenge to the president could thrive. Bu the number of #NeverTrump average voters is comparatively tiny. Unless economic or other such catastrophe breaks out, it’s hard to see a Republican electorate that approves of him ~80% to ~20% opposing the president in their various primaries and caucuses. And that’s if and only if — a huge “if,” to be sure — the party apparatus actually allows it. Odds are that Trump is in for the race in 2020.

What I'm Reading and Working On
I’ve been reading Kevin M. Kruse and Julian E. Zelizer’s Fault Lines: A History of the United States Since 1974 and really enjoying it. On deck I’ve a few more political science books, but I can tell that my pace of reading has already slowed this year. Probably because I’ve been programming so much recently. Back in D.C. next week, I’ll be writing for y'all about evangelical voters.
Thanks!
Thanks for reading. I’ll be back in your inbox next Sunday. In the meantime, follow me online or reach out via email. I’d love to hear from you!
