Washington ? As congressional Democrats prepare to celebrate their first 100 days in the majority, they boast that they have worked more hours, passed more bills and held more oversight hearings than Republicans did when they were in charge.

But when it comes to how many of their top legislative priorities have become law, a different number stands out: zero. None of the six bills that House Democrats passed in their initial legislative juggernaut has made it to the president’s desk.

Still, Democrats say they are proud of the steps they have taken to chart a new course after 12 years of GOP rule, such as stepping up the pressure on President Bush to end U.S. involvement in Iraq and toughening congressional ethics rules.

The 100th day milestone, which arrives April 13 while the House is still on a two-week spring break, amounts to an opening act in a political drama that probably will become even livelier. Congressional Democrats are headed toward confrontations with the White House over many issues, from the war to domestic spending.

Democrats took control of Congress on Jan. 4 after campaigning against “do-nothing” Republicans. To show they were different, Democrats rushed through the House six popular bills in what party leaders calculated was 42 hours, 13 minutes and 28 seconds of legislative time. House Democrats boast they have passed nearly twice as many bills in their first three months as did each of the previous three Congresses.

Scores of bills and resolutions have passed one chamber, often with bipartisan support, including a resolution that would grant honorary posthumous citizenship to Casimir Pulaski, a Polish-born hero of the American Revolution, and a measure that would establish a commission to study creation of a museum in Washington, D.C., dedicated to the art, history and culture of Latinos.

But a major obstacle threatens the Democrats’ ambition of racking up an impressive list of legislative achievements: the closely divided Senate.

A number of the House-passed bills – such as those to cut student-loan interest rates, repeal oil industry tax breaks and lower Medicare drug prices – have stalled in the Senate.

Just how many of the measures will become law is unclear.
