<p>After being boosted by Sen. Dianne Feinstein's decision to stay out of the recall election, California Gov. Gray Davis' strategy of a united Democratic front was crushed Wednesday night when Lt. Gov. Cruz Bustamante decided to enter the race.</p>
<p>Bustamante will announce his candidacy this morning, said his chief of staff, Lynn Montgomery, who declined to elaborate on the reasons for the lieutenant governor's decision. Bustamante pledged in June that he would not run for governor, saying, ``I will not attempt to advance my career at the expense of the people I was elected to serve.''</p>
