In the current political climate, "bipartisanship" mostly refers to giving as much ground to Republicans as possible.
Only after Democrats return to their New Deal-era political strength and aggressively fight back against Republicans can we go into a new era where "bipartisanship" means Republicans giving more ground than they currently do.
Good point. Back in 1956, Eisenhower's Labor secretary Arthur Larson released a book called:
A Republican Looks At His Party.
The book essentially calls on the Republican party to subjugate to the New Deal Democratic party and never go back to it's Conservative roots. The writing is very similar to those of mindless Bill Clinton hacks who call on the Democratic party to go back to being a ''centrist'' party of the 90s that just passes ''market based ideas'' that accommodate the GOP.
The demographics are there, the generational changes are there, the political realignment changes are there: It's time for the Democratic party to shift heavily left and away from the politics of weak-ass accommodation.
