I'm with you on this... For Flynn and Pap, neither had the means for a prolonged fight with the investigation, and from what I understand, Flynn even mortgaged his house to help with legal bills.... Point is, they HAD to scream uncle...
Manafort and Page though are a different beast, both with money and support, both have filed suit to have the charges dismissed on different grounds and I'm sure, willing to keep fighting the charges.... I think our friends on the other side didn't expect this. They planned on couple more rolling over and playing their game, not biting back
