I believe that no matter what a politician believes in, his/her vote for any given bill will be based on keeping their job, and not the bill’s subject. No matter if he/her thinks it will pass or not, make the biggest voting block happy. They love it when they know the other branch of government will vote against it and they get to play with their vote to a particular group.
Stop paying these idiots, make the jobs volunteer, NO remuneration.
I hope this makes sense?
