Hillary Clinton made history this week when she officially became the first woman to earn a major party’s endorsement for president. Tonight, she’ll formally accept that endorsement, putting her on the doorstep of an even greater historical achievement: becoming the first woman president of this great nation. And we can help make that happen.

Clinton’s lifelong record of accomplishments is extraordinary. You are no doubt familiar with many of them. And on Tuesday night, her husband shared some of the other lesser-known but equally impressive passages of her career, in great personal detail. But the most ringing—and most succinct—endorsement of Clinton’s readiness for the job came last night from the man who first battled then worked closely alongside her for years, Barack Obama:

“I can say with confidence there has never been a man or a woman, not me, not Bill, more qualified than Hillary Clinton to serve as President of the United States of America. I hope you don’t mind, Bill, but I was just telling the truth, man.”

If you saw Bill’s face light up after Obama delivered these remarks, you know that he couldn’t have agreed more. We feel exactly the same way.

As we’ve written before—as everyone watching this election ought to appreciate by now—the stakes couldn’t possibly be higher. Hillary Clinton is running against an outright fascist who doesn’t believe in constitutional government, is eager to lash out against American citizens, and wants to withdraw from world affairs in the most destructive way possible. We must not, under any circumstances, allow Donald Trump to become president.

But this endorsement is not merely against our opponent. It is very strongly for Hillary Clinton, too. No one understands the presidency better than she does. No one knows how to fight Republicans harder than she does. And no one will do everything in her power to promote as much progressive change as humanly possible, whatever obstacles there might be, as she will.

There’s something else vitally important, too. If Clinton wins, her victory will send a message to women and girls everywhere. As Clinton herself said in addressing the Democratic convention on Tuesday night:

“I can’t believe we just put the biggest crack in that glass ceiling yet. If there are any little girls out there who stayed up late to watch, let me just say: I may become the first woman president, but one of you is next.”

That’s a message our country has been far too long in delivering. We’re almost there, but Hillary Clinton needs our help—needs everyone’s help—in order to succeed.

So please contribute what you can today to make sure that Hillary Clinton is our 45th president, and the first woman to ever hold the office.
