From Washington Post:

Nelson is also one of several Democrats who have objected to changes Obama has proposed in the farm subsidy system. By stopping direct payments to farms with annual sales of more than $500,000, the White House expects to save about $10 billion over 10 years. But along with Nelson, another Democratic opponent of Obama's annual-sales model is Senate Budget Committee Chairman Kent Conrad (N.D.).

Similar revolts are building against tax changes Obama has proposed, including one to limit deductions that many Democrats privately consider to be a non-starter. Climate-change legislation is months away from emerging, but some Democrats already worry about the political consequences of creating a cap-and-trade system that could result in higher utility bills. Some House Democrats have floated the issue of tariffs on foreign companies -- potentially an explosive trade issue -- to equalize the cost of a carbon cap.

Obama's proposal for Medicare means testing has received surprisingly little attention so far, beyond plaudits from Republicans who have supported the idea for years. The debate over an income scale was especially heated when Congress created the Medicare drug benefit, known as Part D, during President George W. Bush's first term. As a senator, Obama voted against a Medicare means-testing proposal in March 2007.
