She wasn’t First Lady. She was co-President. An unconstitutional position that will lead to more violations of the constitution (when her 2-terming husband is returned to the White House in spite of term limits).
We aren’t supposed to notice that she already held executive branch powers when she tried to force socialized healthcare on “US”.
Since she’s already been co-president, that should rule this quest for more power null and void. According to the Constitution, no one can hold the office of president any more than ten years. She already had eight. Nuff said.
