Let's see what actually happens (we also could defund it in the Obamacare repeal), but we need to defund MURDERERS immediately.
Anything "defunding" Planned Parenthood is DOA in the Senate unless Republicans opt to "defund" it through reconciliation. And even that might be tough for them considering likely defections from Republicans like Collins, Murkowski, and maybe even Heller if a sufficient amount of pressure is put on him.
Also, when it comes to the issue of Planned Parenthood, I really hate the "defunding" terminology that Republicans have successfully implanted in everyones heads. The government doesn't cut a blank check to Planned Parenthood, the law already prevents taxpayer dollars from being used to pay for abortions.
