This is (again) completely missing the point that Democrats are inherently disadvantaged when it comes to this because while they're generally willing to work across the bench, the Republicans mostly aren't. There may be an overlap in policy positions, but when it comes to obstructing the Dems the Republicans will abandon the few principles they have to do whatever they can to get them out. The Tea Party used that approach and it worked. The Republicans never really attacked the ACA on its merits or problems...they just attacked it as Obama's healthcare policy, an approach that by and large worked. They are currently lead by someone who actively disputed whether Obama was an American.
The Dems may be elected to represent their constituents, but they need to realise that if they want to get back into power they need to have a coherent, active message that is strongly against the policies of Trump and the Republicans, otherwise they'll prompt the same sort of apathy we saw in 2016. Compromise is good to a point, but it shouldn't be seen as some hallowed ground to stand on when the Republicans repeatedly ignore it and are in power.
