Will Trump ever be punished for molesting women ongoing the last 40 or 50 years?

Likely not at this point.

Why?

Mostly because the office of the president is more important than any one president. So, just like with Nixon, Trump likely won't go to jail and likely will be pardoned by the next president (maybe Pence or Ryan in the House) when Trump is impeached like Nixon was or was on his way to it when he resigned to protect the presidency and himself ongoing.

So, as probably thousands of men's careers (many that we know who are famous and others)are destroyed we likely will begin to see some of these men commit suicide who cannot afford to go through this and stay alive either monetarily or psychologically. So, for many many men likely it will begin to be more of a bloodbath than it is already while at the same time,  Trump, will not be taken to task or lose anything really because of the office of the president.

So, outside of continuing to pay off women Trump has molested he likely will go on like this until he dies flying around the world until he is impeached and then going back to private life and his businesses and with likely 1 billion dollars in tax cuts to his and his families increasing wealth from this tax bill.
