During the 2008 Democratic presidential primary campaign, Clinton vigorously advocated on behalf of his wife, Hillary. Through speaking engagements and fundraisers, he was able to raise $10 million toward her campaign.[320] Some worried that as an ex-president, he was too active on the trail, too negative to Clinton rival Barack Obama, and alienating his supporters at home and abroad.[321] Many were especially critical of him following his remarks in the South Carolina primary, which Obama won.
