Among Protestant Republicans, 2/3 of those who attend church once a year identify as evangelical.
Among Protestant Democrats, 2/3 of those who attend church more than once a week identify as evangelical.
In other words, among Republicans evangelicalism is a political lifestyle brand, not a real religious belief. Among Democrats it's the opposite.

It is vitally important to understand these distinctions, in part because it can explain why Evangelical political action can be so cruel and often so disconnected from biblical ethics. Why? One answer is found in the simple reality that not only are vast numbers of white self-described Evangelicals unmoored from scriptural truth, they don’t know biblical ethics at all.
A guy memorizing Phil 1:1-18 with us told me he was getting so much from it, he read it to a group recently. Got called a liberal. Gonna tell you right now, a lot of folks putting a checkmark in the Christian square are completely out of touch with the actual Jesus of Scripture.
A pastor told me he cited “Turn the other cheek” and dealt with an outraged guy asking him why he was spouting liberal propaganda.
continuing to quote from the article:
I know these are anecdotes, but it is still absolutely, 100 percent the truth that politicians and activists who seek to mobilize white Evangelicals are trying to mobilize millions of people who do not know or believe scripture and are thus not persuaded by appeals to scriptural principles. As political operators, those politicians and activists often feel they have to appeal to Fox News or talk radio talking points because the biblical argument simply will not resonate. It’s speaking to their audience in a foreign tongue.
Combine the huge, unchurched “Evangelical” mass with a potent neo-fundamentalist movement that is steeped in angry Christian nationalism, and politics and religion can easily become a God-and-country branding exercise. And in that effort, the actual Bible can be an obstacle, not an asset.
