More than a year removed from the White House, former President Barack Obama is still the Democratic Party’s most powerful fundraiser — a prowess that will be on display when he appears in Atherton on Friday for a luncheon where the top ticket is $237,000 per couple.

It costs a minimum of $10,000 per person to grab a plate.

Obama will appear at the Atherton home of Liz Simons (daughter of hedge fund billionaire James Simons) and her husband, Mark Heising, said a source familiar with the event. Simons was one of the Bay Area donors who helped bankroll a campaign supporting Stacey Abrams, winner of last month’s Democratic primary for governor in Georgia. Abrams would be the first African American woman to lead a state in the nation’s history if she prevails in November.

Obama will be raising money for the Democratic Congressional Campaign Committee, which is leading the party’s efforts to flip 23 Republican-held seats nationally, including several in California, and retake the House.

For the price of a top ticket, donors will be able to chat with Obama in a small group — perhaps a couple dozen people. They will also get to take a photo with the former president, Obama, preferred seating to the lunch and an invitation to House Minority Leader Nancy Pelosi’s annual Napa Valley Weekend and Issues Conference in August.

Pelosi, D-San Francisco, and Rep. Anna Eshoo, D-Palo Alto, are also expected to be at Friday’s fundraiser.
