If there's a political motive in not choosing an American pope until now it's that for most of American history it wouldn't have granted them any influence over American politics. If there's a personal motive it's that until recently they felt insulted that America went for almost 200 years before finally electing a Catholic president.
Tangent: Protestantism is not a religion. The religion is called Christianity. I have seen this trend for quite a while of Protestants (or people born in Protestant countries) of referring to Christianity branches as religions. I find it very segregational. The whole point of all the branches is the same guy whose name begins with C.
But yes, given the state of America today, having an American pope will definitely be an interesting development in the context of many lobbying groups wishing for a vaticanised America.
Despite claiming that they follow Christ, our and their definition of "following" is so different that what they do and believe often looks unrecognizable.
The same can be said about the difference between Catholics and Protestants. Despite our disagreements, the Orthodox and Catholic churches still share a lot theologically. The same cannot be said about Protestants (although, that also depends on what denominations you consider).
It's not to say that we don't share any values. We actually do and there are many individual Protestants that behave in a more Christian way than some members of the Orthodox Church.
However, that is not a highly relevant factor. For one reason or another, there are many atheists and members of other religions that do as well. But those still remain clearly separate and would never be classified as Christians.
