While it wasn't something that they directly did with their votes, as they didn't have enough votes in the Senate / House to block the bill themselves -- though they DID keep their caucus united under the banner of ObamaCare. Every single Dem voted to stop the Republicans from moving it. They launched a pretty successful PR campaign telling people that ACA was needed.
Then everyone saw McCain come out and give the thumbs-down, effectively ending the chance the GOP had to remove ACA.
I admit to not really understanding the current status of Obamacare.
Here is an interesting survey.
Yet, only 36% of voters are aware that the Affordable Care Act’s (ACA) Individual Mandate was recently repealed by Republicans (46% of voters incorrectly believe it is still in effect, and 18% of voters do not know). As a refresher, the Individual Mandate was the requirement under the ACA (also know as Obamacare) that individuals must sign up for health insurance or face a tax penalty. The Mandate was repealed last month by Republicans as part of their tax reform bill, and it takes full effect in 2019.
Even among those voters who are directly affected by the repeal of the Individual Mandate — those who are uninsured or buy health insurance in the individual market — awareness of change is alarmingly low: a staggering 44% incorrectly believe the requirement is still in place and another 19% don’t know.
What is even more shocking is that 17% of voters believe that the ACA has been repealed in its entirety (not just the Mandate). This, of course, is incorrect.
Here is the source. It is more than 2 years old...
