The issue that Sen. Murkowski is raising is whether PP should be defunded by means of stand-alone legislation, or by means of language buried as part of a larger bill addressing the ACA. We will need every GOP vote we can muster to address the ACA, because the Dems want us to be blamed for ACA's demise and won't lift a finger to help.
Attaching PP defunding to an unrelated bill is a time-honored tactic to kill the unrelated bill. And that is, IMO in the case of the ACA, an invitation to political suicide. Besides, I think it's more honest, and politically transparent, to vote directly to defund PP.
Listen to Sen. Murkowski, folks, she speaks with wisdom and pragmatism. She like you all opposes the use of taxpayer money to finance abortions. But there's a right way and a wrong way to do it.
