That's not even being consistent within a couple of paragraphs.
Obama (A democrat) compromised on his healthcare plan because that is what he could 'get done'. You just proved your own opinion is incorrect, in your own words.
Did Obama compromise with Repubs on healthcare, answer, no they weren't involved. That is what he could get done within his own party.
Also for what it's worth here in the UK Obama would be a right wing politician, your opinion of what constitutes right wing and left wing politics appears to be about as skewed as your opinion that "Dems never compromise"
Its really not worth much.
