When you go up against the Clintons, you'd better have a clean background. Apparently Donald's people thought this wouldn't see the light of day or blow over as a nothingburger. If there's darkness in an opponent's background, damn well bet Clinton, Inc. will find it, exploit it and flush it into the open at the most inopportune time.
As much as I despise the Clintons, they have a team of oppo researchers that's second to none. They are brutally effective, thorough and to-the-core professionals. That noise about "well, Donald's imperfect, but who isn't" has once again been put to the lie. Yes, it's unfair the media gleefully trumpet this far more than if a democrat had been the offender. The key is: don't nominate someone with such a checkered background and you won't spend 75% of your time on defense.
Trump is going to lose this election by by what is shaping up daily to be an increasingly large margin. What's truly unfortunate is virtually any one of the other 16 candidates would've been far more competitive vs Clinton. Nominating a walking disaster like Trump
is going to be regarded as a horrendous error of historic proportions.
