Keith Mason is the founder of Personhood USA [1] which was launched following the 2008 Colorado for Equal Rights Campaign. The intent of this campaign was to define the term "Person" as used in the Colorado Constitution as starting from the moment of conception, thus in theory outlawing abortion.
Personhood USA has assisted political efforts to constitutionally define personhood in all 50 states.
Mason began organizing other young activists in 2000 with the Campus Life Tours where he along with other activists educated students about abortion. These tours visited over 500 colleges nationwide and over 1000 high schools as well.
Mason also organized the "Truth Truck" project for Operation Rescue[2]
