State Sen. Tom McClintock will tout support from primary rival and former U.S. Rep. Doug Ose in a campaign piece hitting mailboxes in California's 4th Congressional District this weekend,

In a press release, McClintock (R-Thousand Oaks) noted how Ose, a Republican from Sacramento, called to endorse him as soon as McClintock defeated Ose and two other GOP candidates in the June 3 primary.

"When it comes to the issues that matter to us, there's simply no comparison between our candidates for Congress," Ose states in the mailer. Ose previously represented California's 3rd Congressional District until 2004, when he retired from the seat.

The mail item will also detail what McClintock called the liberal policy positions of his Nov. 4 opponent, Roseville Democrat Charlie Brown. At the top of the list is McClintock's call for more offshore oil drilling and Brown's opposition to drilling, though Brown has said in recent weeks that he supports drilling but thinks it should be part of a more comprehensive energy plan.

Among the other differences highlighted are McClintock's support for a "no new taxes pledge" against Brown's call for more federal spending, McClintock's desire to complete a wall on the U.S./Mexico border to stop illegal immigration against Brown's support of immigrant amnesty, and their differing positions on Proposition 8, which would ban gay marriage in California.

McClintock and Brown are competing to replace U.S. Rep. John Doolittle (R-Roseville), who chose not to run for re-election amid a federal investigation into his fundraising.

The Pindell Report on Politicker.com rates the race as "likely Republican."
