SACRAMENTO -Political campaigns are increasingly becoming all-in-the-family affairs in California.Ten relatives of current or former lawmakers are running for state legislative or congressional seats this year, including the husband, brother, mother, son, wife and ex-wife of sitting lawmakers.And 19 former lawmakers are trying to revive political careers with campaigns for the Legislature or Congress.In most cases, the situations are byproducts of California's term-limits law, said Allan Hoffenblum, publisher of the "California Target Book," which analyzes legislative and congressional races.The limits, adopted by voters in 1990, allow state lawmakers to serve up to two four-year terms in the Senate and three two-year terms in the Assembly. There are no term limits for members of Congress.Term limits will open 34 legislative seats this year, and three other Assembly members are running for the Senate instead of seeking re-election, clearing the way for wholesale changes in both houses.Having a family member run for one of those soon-to-be vacant seats enables a termed-out lawmaker to remain part of the "political scene" even if they're not holding office themselves, Hoffenblum said."Bill and Hillary are not the exception," he said. "It's more common than people realize."The primary election will decide most races because the way most districts are drawn gives only one party a real chance of winning. Here are some of the hottest campaigns on the June 3 primary ballot:DOOLITTLE SEAT Former Rep. Doug Ose, R-Sacramento, and former state Sen. Rico Oller, R-San Andreas, are among the Republican candidates running for the congressional seat being given up by Rep. John Doolittle, R-Rocklin, who abandoned his re-election campaign while under investigation in a congressional lobbying scandal. State Sen. Tom McClintock, R-Thousand Oaks, said he also is considering getting into the race.HUNTER'S SUCCESSOR Rep. Duncan Hunter, R-Alpine, made a failed run for president this year rather than seek a 15th term in the House of Representatives. His son, Duncan D. Hunter, is one of four Republicans running to succeed him.LANTOS' REPLACEMENT Former state Sen. Jackie Speier, D-Hillsborough, is running to replace the late Rep. Tom Lantos, D-San Mateo, who died in January. Stanford University law professor Lawrence Lessig is considering challenging Speier for the Democratic nomination. A special election will be held April 8 to pick someone to serve the rest of this year. The seat also will be up for grabs in the June primary.NIELSEN RERUN Former state Senate Republican leader Jim Nielsen is trying to make a comeback, nearly 18 years after he lost a bid for a fourth term in the Senate.
