(CNN) Democratic Rep. Tim Ryan -- whose name has been floated as a potential opponent to House Minority Leader Nancy Pelosi's re-election bid -- said Wednesday that he hasn't decided yet whether to mount a Democratic leadership challenge but that he believes Democrats need a shake-up. "Look, the Obamas are gone. The Clintons are gone. The Bidens are gone. Harry Reid is gone. There's no one at the (Democratic National Committee) now. We've got to -- we've got to say, what's America 2.0 look like?" Ryan said in an interview on CNN's "New Day." "We've got to re-evaluate what we're doing as Democrats, especially in the congressional campaign," the Ohio Democrat said.Tim Ryan is weighing a challenge to House Minority Leader Nancy PelosiRyan says Democrats need new messaging to win over working-class voters
