Meg Whitman has built a massive lead in the GOP Senate primary, and she also a small edge in the general election, according to a new poll.

The independent Field Poll shows Whitman with a 63-14 over state insurance commissioner Steve Poizner in the primary. In the general election, she leads state Attorney General Jerry Brown 46-43.

Whitman has gained double digits on both Brown and Poizner since the January Field Poll.

A competitive governor's race is good news for GOP efforts to unseat Sen. Barbara Boxer (D-Calif.), but right now that governor's race is the much more attainable GOP goal.
