I don't place blame on McCarthy.   Seems that under the Biden administration the angst has grown huge.  So many issues where Joe's policies themselves have produced anger.   His border policy suffers hugely from both sides.  His extreme green energy policy has again hit both sides, by pushing inflation high, and without any relief.   And his blindness and deafness towards crime, policing & prosecutions are a third huge downer.  

Such policies have pushed feelings to the cliffs edge, folks are worried &nervous and this has led to snap judgements.  So the Repubs lashed out, with McCarthy being canned.  An ill considered decision, IMO.
