We had people on this very site predicting the end of Republicanism nationwide before Trump won and the House and Senate stayed (barely) Republican while ignoring all those 'red' Governorships and State Legislatures throughout the rest of the country.

We will always have those who " trust in a narrow ideology" and rely on "group think" on both ends of the spectrum.  It is a secular kind of religion for them.  How rabid they are tends to depend on how badly they are losing.  

In 2008? The ACA?  Pelosi and Reid shoving it down the Republican throats!   More ego than ideology, in my judgement.  Her arrogance of commuting to and from  San Francisco in Air Force One says a lot to me about Pelosi.
