See #17
What would be an interesting counter-argument to make is that if Manafort is the key, then based on his limited involvement in the convention delegate management process, it would be surmised that he colluded with Russia to influence Trump beating back Ted Cruz at the convention, not Trump beating Hillary Clinton in the general election.
Both are ridiculous arguments to make, but the convention fight would be more in Manafort's sphere of influence.
The new meme should be "Manafort colluded with Russians to defeat Ted Cruz, not Hillary Clinton!"
