Obama had a lot of Manchins and Sinemas to deal with.Blanche Lincoln,Mary Landreiu,Ben Nelson,Joe Lieberman,Mark Pryor etc and still got 60 votes in The Senate for it.
You listed five Senators, Obama still had 50 plus votes and he could afford to lose eight senators. And ACA was passed with reconciliation because he couldn't get 60 votes. Do you think Biden can even get 49 votes for any of the progressive bills?
He still got 60 Senate votes in The Senate for Obamacare,including multiple votes from Manchin/Senima type Dems.Not all Democrats are weak and spinless with no courage to fight like Biden.
