Do they expect gratitude? Obamacare hasn’t been a major piece of marketing in a long time, except when Republicans demand it be repealed.
In fact, that’s revisionist history: Democrats were heavily punished for Obamacare by voters, not rewarded. Polling showed that the farther left public option, called “death panels” by the right, was even less popular. The left, as is typical, quickly abandoned Dems to “teach them a lesson”, and we had 8 years of “Tea party” crazies controlling congress.
I am not touting it. The specific claim we’re discussing is whether voting for democrats cause right leaning policies compared to voting for republicans. It didn’t. Nothing you’ve said has addressed this point.
