Bongo! Precisely what you have been evading. The definition used by the Senate was the one used by the First Congress:
"Whereas such limitations would be inconsistent with the purpose and intent of the `natural born Citizen' clause of the Constitution of the United States, as evidenced by the First Congress's own statute defining the term `natural born Citizen';" [SR511]
And the First Congress used a definition that required both parents to be citizens.
And that is the same definition used throughout the SR511. Read it sometime.
Really now? You wouldn't make that up would you? Quote it.
"And that is the same definition used throughout the SR511. Read it sometime."
No definition is used "throughout".
