The dismal results caused Gephardt to drop out and later endorse Kerry. Carol Moseley Braun also dropped out, endorsing Howard Dean. Besides the impact of coming in third, Dean was further hurt by a speech he gave at a post-caucus rally. Dean was shouting over the cheers of his enthusiastic audience, but the crowd noise was being filtered out by his unidirectional microphone, leaving only his full-throated exhortations audible to the television viewers. To those at home, he seemed to raise his voice out of sheer emotion. The incessant replaying of the "Dean Scream" by the press became a debate on the topic of whether Dean was the victim of media bias. The scream scene was shown approximately 633 times by cable and broadcast news networks in just four days following the incident, a number that does not include talk shows and local news broadcasts. However, those who were in the actual audience that day insist that they were not aware of the infamous "scream" until they returned to their hotel rooms and saw it on TV.

Which candidate, after dropping out, went on to endorse Kerry?
