I don't think that Trump is going to be able to recover from this tax issue, even though he did what any other business would do with a loss. Hell, I've done loss carry forward's for just a few hundred dollars.
The media isn't going to explain all of this to the public, and Clinton won't let up (nor will the media). She's already gone back to leading in Ohio and other states Trump only a week ago had taken from her.
Between the tax issue, the Miss Universe concocted story, and Trump's self-destructive behavior, I don't see how it's possible to recover in just 34 days.
As much as I hate the Clintons, and hate Hillary more than Bill, I have to admit that they played this masterfully. The preparation and execution of the Miss Universe "controversy" was flawless. Of course, it's essential to have a compliant media in order to execute such a play. Likewise, I'm sure that the media was primed and ready to go with the tax story, and I would not be the least surprised if it were Clinton or even the IRS that supplied the 1995 return.
Trump is largely responsible for his lot in this race, but I think what's happened with his scandals goes to prove that an outsider can never win in DC. The game will always be rigged.
