Washington ? An independent senator counted on by Democrats in the health care debate showed signs of wavering Sunday when he urged President Barack Obama to postpone many of his initiatives because of the economic downturn.

“I’m afraid we’ve got to think about putting a lot of that off until the economy’s out of recession,” said Connecticut Sen. Joe Lieberman. “There’s no reason we have to do it all now, but we do have to get started. And I think the place to start is cost health delivery reform and insurance market reforms.”

The Senate requires 60 votes to overcome a filibuster and advance a measure to an up-or-down vote. Senators from both parties said that Democrats might use a voting tactic to overcome GOP opposition, abandoning the White House’s goal of bipartisan support for its chief domestic priority.
