I think you are all hitting around the answer. It was a counter to allred and wasn’t necessary. Though he may have been better off simply cancelling his announcement based on the judge’s ruling in boston. I think he has some documentation of some kind.
If he had the docs, he’d want them to come out the same day as whatever zobama’s surprise is.
The October 31 was telling. Why set a date specific if he’s not planning to moe forward in some other way?
Trump knows the Axelrod sleaze play will come in the last week. The Romney version of the Bush DWI. That’s when he dumps his docs. Both stories covered is a wash.
I think it’s poor grades and Marxist classes. If it were a disqualifying “trump card” he’d have already played it.
Romney’s campaign could also want Libya to stay the main issue a few more days. They may have told Trump to delay. Trump knows Obama can’t accept this offer so it’s a push for now.
