He veils it

What does that mean? That he's actually angry but hides it, or that he's not angry but others are? And what would they possibly be angry about?

...and exaggerated.

Perhaps he recognizes that his own campaign isn't immune from this political trait.

The 'angry ones' are Tad Devine and Jeff Weaver. That's their job, and they do it well.

and I was in Vermont when he first came on the political scene. He's not angry, he's passionate. He's got a great sense of humor, by the way, and for many years turned up for the annual cow milking contest at the "Strolling of the Heifers" in Brattleboro.

years of speaking in rooms with shitty sound systems.
