Massachusetts Senate poll loss threatens Obama agenda
Republican Scott Brown has won a shock victory in the race for the US Senate seat in Massachusetts left vacant by Democrat Edward Kennedy's death.
The result is a huge blow to President Barack Obama, whose healthcare reform programme is now in doubt.
Democrat Martha Coakley conceded she had lost the race after early results gave Mr Brown a healthy lead.
The Republican win has robbed the Democrats of their filibuster-proof 60-seat majority in the Senate.
This will make it much harder for Mr Obama to pass a healthcare reform bill - the most important domestic policy objective of his first year as president.
The BBC's Paul Adams, in Boston, says Ms Coakley's defeat is a humiliating blow for the Democrats and their agenda, and a deeply unwelcome anniversary present for President Obama a year after his inauguration.
But it's fun...
"... another one bites the dust."
