The president and congressional Democrats meet Wednesday to narrow some of the differences between the House and Senate health care bills.
Party leaders say they're likely to abandon a House-approved surtax on the wealthy. But a new tax on high-value health insurance plans is still on the table.
Labor leaders say the tax would hurt union members -- who receive lower pay for better benefits.
The 40 percent tax would fall on employer health plans worth more than $8,500 for individuals or 23-thousand for a family.
Meanwhile, a new CBS News poll shows President Obama's handling of health care has hit a new low.
Only 36% of Americans feel he has done a good job reforming health care.
