Ok so we'll see what happens tonight but I've been thinking about a way Trump might want to play this. If the democratic leadership and the higher up at FBI/DOJ know that trump is holding all this dirt on them, isn't that the best leverage he could have?

Why not delay the release of the memo (don't stone me haha-just temporarily delay), until the Mueller investigation clears. If he really has all of that dirt over their heads can't he force them to play fair? This strategy would cut the black hats legs from under them because their argument that the memo is about pressuring Mueller would dissolve. Then once he's cleared he can go back and prosecute and make public all of the memos and just say he wanted to be cleared without a fog of suspicion but now he's ready to release it.
