(CNN) — America’s immigration system is broken, but only a bipartisan political movement can fix it, President Barack Obama said Monday.

“The idea of doing things on my own is very tempting, I promise you, not just on immigration reform. But that’s not how our system works. That’s not how our democracy functions,” Obama told the National Council of La Raza.

Speaking at the organization’s annual conference in Washington, Obama said passing immigration reform measures will require support from both sides of the aisle in Congress.

“Let’s be honest, I need a dance partner here, and the floor is empty,” he said.

Audience members greeted Obama with a standing ovation, and responded to his discussion of immigration reform by chanting, “Yes you can, yes you can.”

“I need you to keep building a movement for change outside of Washington, one they can’t stop, one that’s greater than this community,” Obama told them.

The speech comes at a critical time for Obama, who is trying to drum up support among Latino voters in the run-up to the 2012 election.

Note to Obama: Here’s one reason nobody wants to “dance with you.”
