Passing Obamacare cost Obama a lot in the polls and a shellacking in the mid-terms, according to your logic, the policies weren't worth it. Comparing Obama to Biden changes nothing about that reasoning.
AGAIN, that's irrelevant - we are not comparing Obama to Biden, we are comparing Obama's pre-ACA numbers to post-ACA. Obama started at higher approval ratings and his numbers dropped a lot after ACA passed. Given your logic, such policy proposals are not worth it.
We are comparing pre and post policy approval ratings, not comparing Obama to Biden. Stick to the point.
Brutal political fights can temporarily lower a presidents approval rating.Not fighting lowers them permanently like Bidens.
Obama was fighting with 58 senators on his side, without Manchin and Sinema, Biden can't even get a single cabinet nominee approved.
