Some day, non-White Protestants will be a larger part of America's Protestant population and -- if other trends hold -- a larger share of the Protestant vote will go to Democrats.
It is true, though, that while White Catholics and Mainline Protestants show the same level of support for Trump, those White Catholics are more likely than Mainline Protestants to vote for Hillary (Mainline or non-Evangelical Protestants are more likely to be undecided don't knows).
Non-religious voters -- those who identify with no religious group -- are overwhelmingly for Hillary, and many of them grew up Protestant.
