Former Vice President Joe Biden is lining up a 2020 challenge to Donald Trump.

Democrats and many in the media believe he is their best shot to boot Trump from office.

But what he is accused of doing to women is very bad news.

Former Secret Service agents allege Biden is a worthy successor to the JFK and Bill Clinton class of Democrat executives who are accused of mistreating women.

An explosive new book reveals that female secret service agents hated being assigned to Biden because he would swim naked.

The Daily Mail reports:

“A new book claims that Vice-President Joe Biden upsets female Secret Service agents by swimming naked wherever he goes.

The book The First Family Detail by best-selling author Robert Kessler purports to tell the behind the scenes secrets of the two most powerful offices in the world as seen by their protection details.

Vice-President Biden, claims the book, is more interested in being seen as a ‘regular Joe’ than the second most powerful man in the world.

Agents say that, whether at the vice president’s residence or at his home in Delaware, Biden has a habit of swimming in his pool nude,’ Mr Kessler writes. ‘Female Secret Service agents find that offensive.’

The naked swimming and the last-minute changes of schedule mean that being assigned to Mr Biden is seen as ‘the second worst assignment in the Secret Service,’ Mr Kessler writes.

The worst says the book is working for former First Lady and ex-Secretary of State Hillary Clinton.”

Biden’s conduct around women has received new attention in the wake of the Harvey Weinstein sexual assault scandal, as well as the allegations that Democrat Senator Al Franken allegedly sexually assaulted a reporter on a 2006 USO trip.

Videos surfaced of Biden groping grown women and young girls.

How powerful men treat women is being seen in a new light.

Biden’s groping may have been passed off as playful or just “Biden being your loveable uncle” in past years.

But in today’s world, how he treats women – and the video evidence of his inappropriate groping – will kill his 2020 chances.
