WASHINGTON (AP) Republicans sought to blame Senate Democratic leader Tom Daschle for the collapse Wednesday of the economic stimulus bill. Democrats said the true culprit was an insatiable GOP appetite for tax cuts that favor business and the wealthy. The two sides traded shots after the Senate failed to muster the 60 votes necessary to end debate on competing GOP and Democratic proposals. That guaranteed gridlock and led Daschle to remove the issue from consideration. The Senate approved a straightforward 13-week extension of benefits for the unemployed, a measure that now goes to the House. by Brad Stutzman
