Tactics split state's top two GOP contenders
Fiorina, trying to unseat Boxer, stays true to her conservative primary stance. Whitman, running against Brown, moves to the center in search of moderate voters.
On the campaign trail at a recent "tea party" event, Republican Senate candidate Carly Fiorina dropped a reference to her husband's guns, chided her Democratic opponent for vilifying backers of Arizona's tough immigration law and renewed her commitment to offshore drilling and to suspending the state's global warming law.
