GOP support continues slide with Catholics
It has been three presidential election cycles since a Catholic candidate stood for the office, and while some things have changed — not least the pope — the importance of northeast Catholic voters is as important as ever.
According to Vote Cast, the Associated Press’ analysis of the vote, Joe Biden earned a 50-50 split among Catholics in 2020. That’s a stark difference from the significant margin that President Trump enjoyed in his 2016 victory over Hillary Clinton, when he garnered nearly 60 percent of the Catholic vote.
What made the difference this time around?
To answer that question, I turned to the Religion Census data from the Association of Religion Data Archives to examine how the share of Catholics in U.S. counties related to their vote for Republicans in the elections of 2000, 2016, and 2020.
It turns out that while Trump stays on par (or better) with the Catholic vote nationwide, the GOP’s share of the Catholic vote has been slowly dropping wherever Catholics are more thickly clustered. Trump’s 8 percentage point drop from 2016 with these voters — especially in the swing states of Wisconsin, Michigan and Pennsylvania — is a continuation of a longstanding trend.
In counties with very low shares of Catholics, Trump’s 65 percent share of Catholic voters in 2016 outpaced George W. Bush’s haul in 2000 of just under 60 percent. In highly Catholic counties, however, Trump did only slightly better, with about 55 percent of the vote compared to Bush, who was closer to 52 percent.
When I took a closer look, examining only larger Catholic rich counties (where at least 50,000 votes were cast in 2020), there was no discernible pattern. At the county level, too many other factors can affect the direction of the vote, particularly, it seems, what kind of Catholics are dominant.
For instance, on Staten Island, New York, (Richmond County) and the East End of Long Island (Suffolk), whose Catholics tend to be well-settled descendants of 19th-century European immigrants, Trump did much better this year than George W. Bush did two decades ago.
However, in Union County in northern New Jersey, which has a large population of more recent Hispanic immigrants, Trump only earned 26 percent of the vote, down 11 percentage points from Bush’s total in
2000. The same pattern is true in Santa Fe, N.M., where Trump did 6 points worse than Bush.
At the state level, however, the story came back into focus.
In each of the three elections under study, the Republican earned between 55 percent and 58 percent of the Catholic vote. However, as the share of Catholics in the state increases, Trump actually loses votes more sharply than Bush did. In the 2000 election, for every 10 percent increase in the percentage of Catholics in a state, Bush lost 4.9 percent more of the vote.
For President Trump in 2020 that decline was a bit steeper at 5.8 percent.
The Republicans’ ability to draw these Catholics in densely Catholic states, in other words, is declining, but the decline has accelerated under Trump: While the GOP’s declining share among clustered Catholics fell 1 percent from 2000 to 2016, it dropped another 0.50 percent in four years.
To put all of this in perspective, if Pennsylvania had the lighter Catholic concentration of a place like Iowa, the president may have garnered a 55 percent vote margin, all else being equal, in the Keystone State and may well have kept the White House.
