See: Presbyterians divest holdings to pressure Israel
That said, I support Trump or Cruz and my ideal ticket is Trump/Cruz. Something like half or more of the candidates are Roman Catholic. Cruz and Huckabee and Graham are Southern Baptists.
Not all Presbyterians are alike. The difference between Presbyterian Church in America (PCA) and Presbyterian Church USA (PCUSA) is pretty radical. There are between 4 and 5 times as many members of PCUSA churches than PCA churches although PCA is growing rapidly while PCUSA is in decline. The Presbyterians divesting Israeli holdings are PCUSA. Here is a pretty concise summary of doctrinal differences.

While Trump was baptized in a PCUSA church or may attend a PCUSA church, it certainly does not mean that his policies will necessarily reflect PCUSA policy. They don’t actually and the PCUSA has “complained” to him. See

Like the Lutherans, there are several different branches of the Presbyterians. I don’t know to which D. Trump belongs.
