That is a bit more reserved than your initial claim that there was "nothing to link this"(emphasis added by you) to the Conservatives.
Clearly the links are there. The actions are documented. But since most of the people who got the calls don't record their calls, and the people making the call chose not to do so either, we are left without enough evidence to prove any sort of malicious intent.
Huh?
Boy talk about grasping at Ye Olde Straws.
