Pre-Action Prep: Leaning on Dems on ACA and Medicare

I read this little columnfrom Talking Points Memo yesterday on how badly the GOP will want some Dems to join them in ACA repeal and Medicare privatization votes and it struck me that this is definitely something to mobilize around. We need to pressure our more conservative party-members like Manchin and McCaskill to stick with the party on this and not provide the GOP any political cover for stripping millions of people of health care coverage.

 From what I'm reading, the prospect of actually taking health insurance away from millions of constituents is giving some GOP voters and officials serious second thoughts. Obviously, my biggest hope is that we can stop any repeal of the ACA and privatization of Medicare from happening and I think that keeping up pressure on Dems will help since GOPers know that making these moves unilaterally would hurt them in the polls. Aside from targeting our Senators and Reps, what can we do to pressure conservative Dems?
