Every female Democrat in the U.S. Senate — except one — showed her support for Hillary Clinton’s presidential run on Monday at Washington D.C.’s Hyatt Regency hotel.

Participants included Mazie Hirono of Hawaii. Elizabeth Warren of Massachusetts, who has not yet endorsed a candidate, was the lone no-show.

“It was a power display unlike anything seen so far in the 2016 presidential race,” The Hill opined, adding, “Lined up behind Clinton on the ballroom stage were 13 of the most powerful women in America, all supporting her run for president.”

Clinton, the former secretary of state and first lady, is also a former senator from New York.

Donations ranged from $250 to $2,700, the latter figure deemed a “champion” level that included a photo with Clinton. It was $10 cocktails and $8 for glasses of wine.

“Event co-hosts who raised $10,000 were invited to a post-event dinner with Clinton and the senators,” The Hill said, “while hosts who raised $27,000 could join the dinner and become members of the Hillstarter program for top Clinton fundraisers.”

In an email message from her Senate campaign last week, Hirono wrote, “We always have a great time when the women of the Senate get together, and this party benefits a special cause: helping one of our own get to the White House.”

The senator’s pitch encouraged supporters to clink on a link to add their names “for a chance to win a free trip for you and a guest to join us.”

Clinton is running against Sen. Bernie Sanders of Vermont and former Gov. Martin O’Malley of Maryland. The Republican field is in the double-digits.
