From the Times: Some of General Clark's supporters said he was likely — but not certain — to end his bid for the presidency should he lose Virginia and Tennessee, two states where he has invested a huge amount of time, prestige and money. So far, General Clark has won only one state, Oklahoma, and by a very slim margin. Several national Democratic leaders said that should he lose again, the general would probably come under pressure from the quarter of the party that encouraged his candidacy — the Bill Clinton camp — to clear the field for Mr. Kerry. By contrast, Mr. Edwards and his aides rejected admonitions from some Democrats that he step aside if he loses. Instead, he said he would push on through Wisconsin on Feb. 17 and on to March 2, when Democrats in 10 states, from New York to California, will choose 1,408 delegates.
