Mama June -- America Needs a FEMALE President

There's been ENOUGH testosterone in the White House -- it's time for a WOMAN to lead the country, this according to Mama June.

The "Here Comes Honey Boo Boo" star was leaving an NYC Barnes & Noble (yes, they still have those) ... when June explained why the next Commander-In-Chief needs to have lady parts.

Fun Fact -- June and her family recently visited the White House in D.C. ... and Mama says one of her daughters was so impressed, she left a "sticky note" for President Obama.
