John, I’m familiar with the non-winner take all nature of the European democracies and why third parties in American politics have either knocked out a contender or have mostly vanished. I agree that the emergence of a Christian Democrat party is a longshot, but I still think it could arise under certain circumstances. Bioethics is a possible driver.
James, I agree with you that there are some very distinctive characteristics of the American Christian population and their political preferences. A CDU party here would surely look somewhat different from the European versions.
