Actually, that's not true. There is no clear definition of "natural-born citizen" but it is generally agreed that it amounts to a person being born on US soil, whether in the states themselves or abroad. Obama's mother's citizenship is therefore irrelevant, and has been ever since the last Naturalization Act was repealed in 1802. The reason no one cares about McCain's place of birth is that he was born on an American military base, which is US soil no matter where in the world it is. But I do agree that this Birther stuff is nonsense. I'm not so quick to say it's racially motivated, because Obama isn't the first candidate to have his citizenship question (in fact, he's the first major candidate of color to endure such accusations). We've all seen how Republicans operate, this should be no surprise.
