He was bitter and ugly and was clearly just showing the same lack of acceptance of their side losing as many other emotionally brittle far lefties. He has broken with established decorum and a long history of respect for fellow members buy putting his far left agenda first.

The American people are watching these temper tantrums, and if the far left thinks they are being viewed favorably for all these horrible behaviors they have another thing coming.
There is a good reason Democrats have lost over 900 elections under Obama’s leadership.
