Trump Card

[H2O Man]

11. Under normal circumstances,

that's definitely true. And it may well hold under the current, extremely unusual circumstances.

However, those smaller fish can not be portrayed as solid witnesses, even if they turn on Trump. It seems unlikely, for example, that either Flynn or Sessions documented any conversations, etc, with Trump, in the manner that Comey did.

More, any case per the Russian bit is much more difficult to prove, than is obstruction. And the witnesses in an obstruction case are, without any question, far stronger than in a Russian ties case. That includes Comey, as well as two other intelligence directors and a host of FBI officials who would provide evidence supporting Comey.

In my opinion -- as a member of the Democratic Party -- there are significant political advantages in having it drag out another year, per the 2018 elections. But if things unfold quicker, it would not surprise me. Either way, obstruction will be the primary charge, and there is not much more preparation needed to present that to a grand jury.
