A posh Palm Beach County manse once used to host fundraisers for American presidential candidates, including the late Sen. John McCain, is now on the market for $7.99 million.

Former owner Lothar Mayer, the 87-year-old ex-president of Liberty Hardware Manufacturing, hosted parties that were also attended by Democrats, like former President Bill Clinton and Sen. Joe Lieberman.

The home, at 6017 Old Ocean Boulevard, in Boynton Beach, is currently owned by French-Canadian magazine and art encyclopedia publisher Yves Moquin.

The six-bedroom home is a mighty 13,376 square feet and comes with ocean views.

It sits on two thirds of an acre and also includes a guest/caretaker’s cottage and a four-car garage.

Inside, there’s a chef’s kitchen, a catering kitchen, a billiards room with a bar, a home theater and a 2,000-bottle brick wine cellar.

There’s also a pool, a spa and an outdoor kitchen — and a dock at Boynton Marina.

The listing brokers are Douglas Elliman’s Val Coz and Jeffrey Wilson.
