"Right to Chose" is a code term for Pro-Abortion. No other choice is intimated or intended. It's a Litmus test for "Progressive" "Liberal" candidates.
Of course Progressive means pushing progress towards total government control and a socialist economy, and Liberal means allowing unlimited bureaucracy. But, hey, they change the words. It's like Gay used to mean (Prior to 1975) light hearted and happy. Now, it just means perverted sexually.
