Don't be too concerned with being able to defend every piece of this brouhaha and all the accusations.
It's not like the left and MSM play the game that way, yaknow.
I know folks like to seek and hold the high and moral ground but perfection of argument is not always achievable initally if ever.
The DOJ could help all of us out here by releasing who exactly is or has been pegged or is being placed under the scope.
Then we could be more surgical and forceful in making the argument in each instance with certainty and not be held back from action by uncertainty.
This is coming from someone who prefers to not use a broad brush as a rule or first much less last resort as the MSM and many pundits are already doing..

One source is the National Republican Sen Commit which has links to how they came up with the numbers:

The other is the capital eye that has a different set of numbers:
