How is she on the National issue? Immigration, etc.? I hear she adopted two hatians. Not a good sign.
That's what concerns me about her, too. Not likely she places any value in the US remaining majority White.
What does the constitution say on the matter?
The very first immigration law passed by Congress in the US, and passed under the US Constitution, specified that candidates for citizenship must be Whites of good character, so it's clearly not unconstitutional. That law stood for a very long time, and was never found unconstitutional.
