The Republicans' upset Senate victory in Massachusetts has given California Republicans hope that they also can capitalize on voter frustration.
They have set their sights on Democratic Sen. Barbara Boxer, who is seeking a fourth term this year.
Democrats have a different point of view and say Boxer is a proven campaigner who will be ready for a rough-and-tumble general election in November.
State Assemblyman Chuck DeVore says Republicans have a reason to be optimistic because Massachusetts voters are more liberal than in California.
