In a meeting with House progressives today, Obama made the pitch.
Speaking to reporters in the Speaker's lobby off the House floor, Congressional Progressive Caucus Co-Chair Raul Grijalva (D-AZ) said the President reminded them that "If this opportunity passes, much of our agenda, on the progressive side...it would be difficult, if not impossible for a generation to get back to this issue."
I asked if the message was convincing to those in attendance.
"It's pretty compelling," Grijalva said.
That's a significant change from his tone earlier in the week, when Grijalva said he was inclined to vote against the bill from the left.
