Yes, exactly

Simon Rosenberg offers an insightful take on "the meaning of" Lieberman's defeat:

In this new era, partisanship is a virtue. The conservatives rise to power, and their utter failure to govern responsibly or effectively, requires a new progressive politics of confrontation, not accommodation. This new politics may be uncomfortable to those used to an America governed by Democrats and progressive values, but for our politics and values to triumph progressives must and are learning how to resist “cutting deals,” working to “get things done” on terms set by an irresponsible governing majority.
. . .
I have great sympathy for those wishing our politics could be more genteel, where both sides could come together to work things out for the common good. But we live in a different time, and our the rising partisanship in the Democratic Party is a necessary, pragmatic and I believe virtuous response to the circumstances we face today at the dawn of the 21st century.

It's not your father's Republican party, Joe. To the barricades, or out of the way!
