Former President Bill Clinton is participating in an event with the Obama campaign where donors are entered in a chance to meet with him and President Barack Obama in New York. Mr. Clinton sent an email to Obama supporters this morning encouraging them to pay up for a chance to spend the night with the pair of presidents and explaining why he thinks Mitt Romney must be defeated.

"If our opponent succeeds, so much of what we've fought so hard for will be rolled back. Health care reform--which many presidents, including me, tried to pass and couldn't--will be gone. Same goes for the opportunity for millions more Americans to afford to go to college, and a growing economy that works for middle-class families," he wrote. "Our opponent is actually advertising a more extreme version of the policies that got us in trouble in the first place: policies that will leave us with more debt, weaker regulations on risky investments, and fewer jobs."

Mr. Clinton also criticized the Super PAC spending in the race.

"We're facing a tidal wave of anonymous, unlimited spending. The other side has pledged to throw more than 1 billion dollars into tearing down our president," he said.

Read Mr. Clinton's entire email below.

"I've been in President Obama's shoes before -- less than six months to go before an election to let you finish what you started. It was tough enough back then, but this election is going to be tougher.

We're facing a tidal wave of anonymous, unlimited spending. The other side has pledged to throw more than 1 billion dollars into tearing down our president.

It's unprecedented.

Fortunately, so is the grassroots organization you're building.

Pitch in what you can today to strengthen the campaign -- and you'll be automatically entered to join me and President Obama in New York City, with the campaign covering transportation and accommodations.

If our opponent succeeds, so much of what we've fought so hard for will be rolled back. Health care reform -- which many presidents, including me, tried to pass and couldn't -- will be gone. Same goes for the opportunity for millions more Americans to afford to go to college, and a growing economy that works for middle-class families.

Our opponent is actually advertising a more extreme version of the policies that got us in trouble in the first place: policies that will leave us with more debt, weaker regulations on risky investments, and fewer jobs.

All of that's at stake between now and November, but here's why I'm feeling good about our chances: I know people like you have the President's back.

And I can't wait to meet you. I hope you'll give it a shot:
