In a way, Trump is like the mirror universe of what centrism (which is a Washington pundit unicorn) is supposed to be. He's socially conservative and economically liberal. Okay he doesn't fit neatly into either of those categories. He's not religious. He probably doesn't care much about gay rights either way. He loves the Richie Riches, at least the ones who are nice to him.
He's racist (in rhetoric, who knows or cares what he actually thinks) and he's not calling to dismantle the minimal welfare state this country has. I have no idea what President Trump would be like. Quite bad, probably! But he isn't Fred Hiatt's idea of who a president should be, which is interesting.
