This is the title of an analysis piece by Chris Cilizza today on CNN. Mr. Cilizza’s view of M.T.G. is 

“Greene is a new breed of Republican Members of Congress. She uses her platform not to legislate or move up the ranks of seniority or even to befriend colleagues but rather to build her brand. And that brand is as an unrepentant defender of former President Donald Trump and his “America First” policies.”

I would say more. Green is one of a coterie of Republicans in Congress who will do anything to keep themselves before the public eye. They cannot achieve this by being good legislators, so they must resort to other ways of attracting attention. They remind me of bad little boys competing to see who can perform the grossest act, like pissing the farthest, farting the loudest, belching on cue, pooping on neighbors’ porches, and so on. 

But these “bad little boys” are not going to grow up, and it is up to the Republican adults in Congress to discipline and restrain them. But those adults are inhibited by their own slavish behavior and their acquiescence in the Big Lie, and so they are not in a position to tell anyone how to behave.
