Washington ? Undaunted by a Senate setback, Democrats appeared increasingly confident Monday they will be able to take advantage of Americans’ anger at Wall Street and push through the most sweeping new controls on financial institutions since the Great Depression.

The Senate, in a 57-41 vote, failed to get the 60 supporters needed to proceed on the regulatory overhaul. One Democrat, Sen. Ben Nelson of Nebraska, joined with the Republicans.

But the evening vote was just part of a legislative ballet keeping bipartisan talks alive. At the end, Senate Majority Leader Harry Reid switched his vote to “no,” too, but that was just a maneuver that will enable him to call for a new tally as early as today. If that failed, Reid planned another vote Wednesday.

Democrats believe that public pressure and the scent of a Wall Street scandal have given them the upper hand. Republicans themselves have taken up the Democrats’ Wall Street-bashing rhetoric and have voiced hope that a bill will ultimately pass. In that light, the path to final approval seems clearer than it ever did during the contentious debate over health care.
