One who hates Christians and knows that Biden is actually a Christian and Trump isn't.
Struggling to imagine the kind of Muslim who would vote for an irreligious philanderer because the other candidate was Christian.
Do you think a Likud supporting Jew would vote for an irreligious philanderer because the other candidate was Muslim? Basically the same principle.
Probably not if the irreligious guy had pushed for a "Jew ban" on travel from Israel, to continue the analogy.
Not saying there's many. Now granted there's plenty of Muslims who support Trump in the Middle East, I'm sure just about all the wealthy Gulf states' leaders support him, but those regimes have next to zero support amongst US Muslims.
