Cashill pointed out in a column last year that in contrast to "Dreams," the Obama writing samples unearthed before 1995 "are pedestrian and uninspired."
"There is no precedent for this kind of literary transformation," Cashill wrote. "It is as if a high 90s golfer suddenly showed up with his PGA card – with no known practice rounds in between."
The evidence Cashill had gathered to that point, he said, "severely tests Obama's claim of a superficial relationship with the self-declared 'communist' Ayers. This appears to be a conscious and consequential deception."
