This is a topic that is particularly relevant to middle-of-the-roaders like

In the mid-1990s, Newt Gingrich came upon the realization that an opposition party would electorally benefit from mindless partisan obstruction, no matter how unprincipled or destructive. By fighting tooth and nail, even against policies they might otherwise support, and rendering government ineffective, they would benefit electorally.
This became standard GOP strategy during the Obama presidency, as the GOP controlled Congress, but the strategy against good faith governance, bipartisan cooperation, and adherence to longstanding precedent on transparency and political responsibility has carried over into the Republicans' current in-power status. This can be best seen in their blatant hypocrisy and refusal to engage in good faith governance on the issues of healthcare and judicial nominations.
During debate on the ACA, Republicans loudly decried the lack of transparency and the lack of bipartisan compromise, despite hundreds of hours of debate and GOP amendments. Then, when trying to pass their own bill (which was universally panned by consumer groups), they actually engaged in the tactics of which they accused the Dems.
Similarly, McConnell and friends bitched and moaned about Kagan and Sotomayor being pushed through, despite the very thorough vetting and disclosure of the nominees, and are now pushing through their nominee in an unprecedented way.
So, when and if Democrats regain power, should we once again ask that they return to the standards of good faith bipartisan governance? If history tells us anything, there is a good chance that the Republicans will continue to obstruct and then, when the GOP regains power, they will resort to the same dirty tricks - and our country will have been made worse for it.
Or should Democrats return the favor and cede the moral high ground to aggressively reverse the insidious and destructive policies pushed by the GOP, and risk an inescapable cycle of unaccountable partisan governance?
