WASHINGTON -- Massachusetts Republican Scott Brown is the new face of change in Washington that's shaking up the Democrats' aggressive healthcare agenda.

After winning big in the bluest state in the union, Brown has Democrats running scared less than a year before many of them face re-election. Now their majorities in the House and Senate hang in the balance.

But the Democratic leadership insists Congress will move ahead with health care reform.

"We will move forward with their considerations in mind, but we will move forward for health care," House Speaker Nancy Pelosi, D-Calif., said.

Republican Sen. John McCain of Arizona said, "The American people have spoken. The people of Massachusetts have spoken for the rest of America. Stop this process."

Democrats are considering scaling things back, eliminating government-run health insurance. They'll be focusing on reforms such as keeping insurance companies from denying coverage to certain Americans.

Another option would simply be putting the Senate healthcare bill before the House. But Rep. Bart Stupak, D-Mich., immediately pooh-poohed that notion.

"If you ran that Senate bill right now on the House floor, I'll bet you would not get 100 votes for it," he said.

Meanwhile, Senate Democrats have to pursue another unpopular policy in this election year.

With government spending on the rise, leaders are pushing to increase the nation's debt limit by nearly $2 trillion.
