I personally am not going to vote because I'm not America, but just to tell a curious fact - In Portugal, the president has to be 35 years old and a citizen of origin. It's pretty much accepted as a good principle. A Portuguese of origin is simply someone with Portuguese lineage. A grandparent or something like that is enough. In theory, someone who acquired citizenship without previous ancestry is never allowed to be president. Of course, there's other requirements as well, so it's not like you discover Portuguese ancestry and can suddenly become president.
