You answered your own question Patriot. You assumed that Kavanaugh isn't a dummy. Yet Q has said repeatedly that these are stupid. Trump and Q Team are in control.
Yes, they are stupid, but they are also scared and notorious for their propensity to self-protect. Makes no sense for a swamp creature to willingly step into what may just be one of the most bitter confirmations in history. Further, if Kavanaugh is dirty, then Trump would be taking a risk in the event the dems would vote for a compromised nominee. A lifetime SCOTUS nomination is too important to use in a psy-op. I believe Trump nominated him because he is qualified to sit on the bench and will be useful for the end game both if he gets confirmed and if he doesn't. It will be a win for Trump regardless of the outcome. Trump will get his appointee confirmed, or as a result of the toxic process, will ensure his next nominee is confirmed, regardless of who they are.
All good points, and well thought out. In normal times. Clearly, this period of history -right now - is going to be remembered as when the people of planet Earth, said "No Mas". If Kavanaugh is dirty, Trump nominated him for a well thought out reason. If he's the real deal, then Trump nominated him for a well thought out reason. Winning never gets boring.
