I appreciate your point but it really doesn’t matter why Boehner and company do what they do. The “why” isn’t all that important IMO. The fundamental heart of the issue is that they repeatedly promise to do things but don’t ever do them. They have a list of excuses a mile long and the real reasons for their political treachery are probably manifold. And even worse is their hubris and arrogance knowing that they get away with it so easily.
Yes, Boehner is gone but the culture of duplicity is still there.
Results are what matter. And they don’t produce anything but pathetic excuses. How people continue to vote for such fraud and failure is beyond me.
I'd say the why matters above all else. Many Republicans repeatedly say one thing during their reelection campaigns, then do something very different once they've won another term. I think most believe correctly that they are dancing to the tune of major donors and pushing or opposing legislation based on what those major donors desire.
The more voters who understand that 'why", the better. We might at some point see more representives elected who will actually listen to the majority of voters rather than the biggest donors.
