Monica Lewinsky is institutionalized and wholly brainwashed by the Democratic Party and the Cabal overall. She knows what they're capable of and probably has intimate/inside knowledge of their criminal dealings. Additionally, having been a homewrecker and rubbing in Hillary's face the fact that she is old, dried up, unattractive, and unwanted by her husband, she likely lives on eggshells with total dedication to the political party that could wipe her out in the blink of an eye. She has an obligation to whore herself publically to the Democratic Party at every opportunity.
