From "Yes, Donald Could Beat Hillary/Conventional wisdom says he has no chance. But what if he blows up all the old rules?" by William McGurn (in the WSJ).
Despite what I just quoted up there, McGurn is in what I'd consider a pretty heavy state of denial. The column ends with:
Sure, it’s possible the GOP front-runner will implode, just as it’s possible all those polls showing Mrs. Clinton with a double-digit lead over Mr. Trump will indeed come to pass. But some of us who never thought he would get this far are a little more reluctant to be so categorical about an election that is still seven months away.A little more reluctant? To be so categorical? You should be completely over your categoricality.
AND: Bernie Sanders has not been a tough competitor. He's been damned nice to her. He only fights on the issues. He holds himself above all sorts of attacks that Donald Trump would unleash with vigor, delight, and — his favorite — unpredictability. And yet Hillary's campaign is portraying Sanders's campaign as unacceptably negative. They're resisting debate because they don't like his "tone." His tone!
How is she going to deal with Trump's tone? Refuse to debate? One of the arguments McGurn examines — arguments for why Hillary is supposed to trounce Trump — is the Clinton will make him look "like an ignorant yahoo" when they debate. Will she even dare to debate?
