Sen.Rubio has publicly spoken: he will not accept the VP nomination.
There are groups around the nation putting together ballot initiatives for the Nov.2012 election that would provide state constitutions with an amendment defining natural born citizen. It would require all persons running for President or Vice President to prove eligibility: that they were born in the USA of USA citizen parents.
The definition of natural born citizen is in the summation to Minor v. Happersett, 1874.
Hooray!
