...I am not a lawyer..
yawn, keep reading, there are dozens of papers/articles on this one subject on both sides of the fence. Remember the same lawyer can usually argue both sides of a case depending on who is paying im.
What I find very interesting is that in the dissenting opinion they foresaw the possibility of someone being born in the US to parents who are not citizens would be eligible for the presidency.
There are exceptions, based on English common law, to that though. Children of diplomats, clergy(from foreign countries on a mission to the US), and children born as part of a foreign army fighting on US Soil.
I do not like this interpretation of the 14th Amendment. But the only way to change it would be to get another case concerning this issue and have them overrule this decision, or base a constitutional amendment changing the citizenship rules.
