Strong point, but with Nixon firing Dole unceremoniously, and installing Bush as the RNC head, Dole might have had an axe to grind. Also, I've read that Dole was put out with the very idea of CREEP, as it diluted his power.
Dole's a good candidate for DT.
There could be one complication, though.
Suppose DT was fed the info by someone else.
Do you think he could actually be a lowly functionary
serving as a middleman?
It could be that even Woodstein doesn't know who the REAL source was.
