In another sign that the world has changed since President Barack Obama took office and Democratic majorities in Congress expanded, the progressive group Campaign for America’s Future has changed the name of its annual Washington, D.C., conference.

[IMGCAP(1)]Known for years as the “Take Back America— conference, the three-day confab, which kicks off today at the Omni Shoreham Hotel, is now known as “America’s Future Now!—

Several Members of Congress will be addressing the conference: Sen. Jeff Merkley (D-Ore.) will talk energy policy, Sen. Tom Harkin (D-Iowa) will weigh in on the Employee Free Choice Act, and Sen. Sherrod Brown (D-Ohio) will look at the future of progressive politics.

At least seven House Members will also be speaking — including Reps. Donna Edwards (D-Md.), Raúl Grijalva (D-Ariz.) and Jared Polis (D-Colo.), who are on a panel about new liberal leaders in Congress. Rep. Barbara Lee (D-Calif.) will be given the group’s America’s Future Progressive Champion Award.

Members might also want to take note of a conference session Tuesday morning called “Staying on Top of Congress’ Shenanigans.— It’s being led by Joshua Grossman, a self-described “social entrepreneur— from Berkeley, Calif., who runs the Web site ProgressivePunch.org, which tracks Congressional votes.
