Put simply, Donald Trump, once the Clown Prince of American politics has become the Most Important Person of American politics today. Outrageous as he might be, he is not just setting the cat among the pigeons. He is the cat among the pigeons. He is setting the agenda and everyone else gets to react to it. As testimony to that, the Republican Party’s leaders, while trying to distance the party from Trump’s outrageousness, are nervous about going the full distance.
