(NECN) - A woman's right to choose is one of the most heated issues in the United States today.

Markey, once supported by pro-life groups, is now staunchly pro-choice and has the support of Planned Parenthood. Lynch, on the other hand, says there is a Constitutional right to abortion, but claims to be pro-life.
