I mean, I was 22 in 2009, I voted for Obama twice, I voted for Democrats up and down the ticket in every election since I've been eligible, and I've been passionate about politics since an early age, owing to my family's strong involvement in local politics when I was growing up.
I understood then and understand now how it passed, what the process was like at the time, the rationale behind Reid and Pelosi attempting to compromise with Republicans, like I get it. At the time it seemed like a great stepping stone to eventual better things, we would get Obamacare now, and once the country recognized that being able to get healthcare without going bankrupt was a good thing, we'd be one step closer to single payer.
Looking back, since the only reasoning for weakening the ACA was in an effort to get Republican buy in and show the American people at large that there was a broad mandate, and every Republican still opposed the weakened bill, there was no reason NOT to use the Democratic supermajorities at the time to bring back the original non-compromised bill.
