All Democrats in the U.S. Senate just voted to preserve funding for the national health care law, with the measure being rejected by a 47 to 53 vote straight party line vote.
The Obamacare defunding vote could be particularly harmful to Sen. Joe Manchin who won a special election in West Virginia last year by convincing voters that he was a conservative Democrat who would buck party leadership.
In fact, weeks before the election, Manchin said he was open to repealing the health care law entirely.
This is a vote he'll have to explain to his constituents when he defends his seat in 2012.
