United States Sen. Kirsten Gillibrand (D-NY), who made feminism and women's equality the main focus of her presidential campaign, on Wednesday became the first female candidate to abandon the Democratic Party's race for the 2020 nomination, leaving 20 candidates still in the running, among them five other women.

In a video posted on her official Twitter account, Gillibrand announced the end of her campaign, which never aroused much interest among Democratic voters; the latest example of the lack of excitement generated by her candidacy was the fact that she failed to qualify for the party's next televised debate.

It was “important to know when it’s not your time and to know how you can best serve your community and country,” Gillibrand said in the video.

US President Donald Trump, who has sneered at the latest casualties in the race to seize power from him in 2020, was quick to react to Gillibrand’s post on Twitter, saying – with more than a hint of irony – that it was "a sad day for the Democrats.”

“I’m glad they never found out that she (Gillibrand) was the one I was really afraid of!” Trump quipped.

The New York senator is the first of six female Democratic presidential candidates to drop out of the race, leaving three other women senators – Elizabeth Warren (MA), Kamala Harris (CA) and Amy Klobuchar (MN) – in the running, as well as Congresswoman Tulsi Gabbard (HI-2) and activist Marianne Williamson.

However, the party's strict requirements for participation in the next Democratic debate, which will take place on Sept. 12 in Houston (Texas), means that the list of Trump's potential rivals is likely to be culled even more in the near future.

Only 10 candidates have met both the criteria of obtaining a minimum number of unique campaign donors and a minimal percentage of support in the polls that are required to be on stage in Houston, including three of the five women contestants (Warren, Harris and Klobuchar).

Rounding out the list are former Vice President Joe Biden, independent Senator Bernie Sanders (VT), Sen. Cory Booker (NJ), South Bend (IN) Mayor Pete Buttigieg, former Secretary of Housing Julian Castro, former Rep. Beto O'Rourke (TX-16) and businessman Andrew Yang.

Gillibrand finished her Twitter post by thanking her supporters and asking them to “now, let's go beat Donald Trump and win back the Senate.” EFEEPA
