Barack Obama spent more than twice as much as Hillary Rodham Clinton on television ads in the race for the Democratic presidential nomination after the Feb. 5 Super Tuesday primaries and caucuses, a University of Wisconsin study concludes.
That helped Obama win 11 states in a row and open what has proved to be an insurmountable lead in pledged delegates.
Obama spent $46 million after Super Tuesday on ads to $20.8 million for Clinton, the study said, using figures from the Arlington, Va.-based Campaign Media Analysis Group. Through the Feb. 5 primaries and caucuses, Obama had outspent Clinton by $4 million.
The Illinois senator has surpassed all Democratic fundraising records in the race, taking in $256 million for the primaries through April 30. Sen. Clinton of New York raised about $173 million. She owed about $10 million at the end of April, in addition to about $10 million she loaned the campaign from her own funds.
