WASHINGTON, Feb 5 (Reuters) - A bipartisan resolution repudiating President George W. Bush's decision to send 21,500 more troops to Iraq failed to advance in the U.S. Senate on Monday, dealing a serious setback to critics of the war. The resolution needed 60 votes before the 100-member Senate could begin debate, but it got 49, with 47 voting against. Although it would not have been binding on the president, the measure was the first serious effort in Congress to confront Bush over the unpopular Iraq war.
