“3 of our first 4 Presidents - Washington, Jefferson and Madison - were dual citizens with France. While serving as US President.”
Of course they were since they grandfathered themselves in. Jeez!
No. Historians are UNANIMOUS that Washington, Jefferson and Madison were not natural born citizens because they "grandfathered themselves in." They were natural born citizens because they were all born in the Colony of Virginia. They continued that natural born relationship with the Colony of Virginia as Virginia became a State and a member of the United States, and as "subjects" became "citizens."
Real historians are UNANIMOUS in this understanding. Only the uninformed, idiots and birthers (but I repeat myself) claim otherwise.
