With time running out before Republicans assume control of the House, Democrats are trying to force votes on controversial issues, chief among them the so called "new START" nuclear treaty.

Democrats need at least nine Republicans to vote yes on START.

Some Republicans already back the nuclear arms deal with Russia.

"Progress on the new START treaty is extremely important for the national security of our country," argued Indiana Senator Dick Lugar.

The deal would reduce both sides' missiles, long range bombers and nuclear warheads, and allow inspections.

President Obama, who signed the treaty in april with Russian President Medvedev, needs 66 Senate votes to get it ratified.

He wants the vote now, before he loses Democratic Senate seats next month.

Most Republicans call that a "rush."

"No senator should be forced to make decisions like this so we can tick off another item on someone's political checklist before the end of the year," says Senate Minority Leader Mitch McConnell.

Democrats counter there have been 21 hearings and meetings.

"We have been on this treaty for a year and a half! Not just for six days," points out Senator John Kerry.

There is a new controversy, however.

Some claim the treaty could ban U.S. missile defense designed as a shield against Iran.

Flush from their repeal of "Don't Ask, Don't Tell", Democrats hope to pass a $725-billion defense bill and a health bill to aid 9/11 first responders.

Since Democrats still control Congress and the schedule, they can keep Republicans here a few more days to work on those bills.
