If what you say comes to fruition, I believe BK will withdraw from the nomination. He won’t, nor will he let his family go through this any further.
Withdrawing will blacken his name FOREVER and it means that Trump will NEVER be able to get another judge passed as long as he is president and beyond, for ANY GOP president in the future!
I wouldn’t blame him for doing so if it all turns in that direction. There comes a point at which it’s not anymore worth the effort.
