President Barack Obama is losing some of his popularity, even among members of his own party.
Conservative House Democrats are balking at the cost and direction of Obama's top priority, an overhaul of the United States' health care system.
A key Senate Democrat, Max Baucus of Montana, complained that Obama's opposition to paying for it with a tax on health benefits "is not helping us."
Another Democrat, Congressman Dan Boren of Oklahoma, told a local newspaper that Obama was too liberal and was "very unpopular" in his district.
In his first days in office, Obama's huge popularity helped him pass a $787 billion stimulus package and fueled his ambitious plans to overhaul the nation's health care system and tackle global warming.
The young, charismatic president's popularity is still comparatively high. But now recent national surveys have shown a measurable drop in his approval rating, even among Democrats. A CBS news survey out this week had his national approval rating at 57 percent, and his standing among Democrats down 10 percentage points since last month, from 92 percent to 82 percent.
