Mimi K. Walters (born May 14, 1962) is a Republican State Senator from the state of California, representing the 37th District since 2012. She previously represented the 33rd Senate District before redistricting forced her to change districts. She also served in the California State Assembly for four years from 2004 to 2008, where she served in the Republican leadership as Assistant Republican Leader and Vice Chair of the Appropriations Committee.
Currently, Walters is running to represent California’s 45th Congressional District, which is being vacated by U.S. Congressman John Campbell. Campbell, along with Congressmen Kevin McCarthy, Darrell Issa, and Ed Royce, endorsed Walters during the 2014 Primary Election. 
Early years and education
Walters was elected in 2004 to represent the 73rd Assembly District, which includes coastal Orange and San Diego county communities of Laguna Niguel, Laguna Hills, Oceanside, Dana Point, San Clemente, San Juan Capistrano, and Aliso Viejo.
Since the US Supreme Court decision Kelo v. New London in June 2005, Walters has been at the forefront of amending California government acquisition and the regulation of private property laws. She introduced two bills, AB 590 and AB 1990, in the 2005-06 session on these topics. After both bills failed in committee by party line votes, Walters became a leading figure in the campaign for Proposition 90. She was named honorary chair of the Save Our Homes initiative campaign. Supporters of Proposition 90 referred to their effort as protecting property rights. The initiative received over one million signatures to qualify for the November 2006 ballot. Proposition 90 failed with 47.6% of the vote.
In the 2007-2008 session, Walters introduced ACA 2, a state Constitutional Amendment to change government acquisition and the regulation of private property by California local governments.
Walters introduced a package of bills in February 2011 to address the California pension crisis, SB 520 through SB 528.
In an op-ed written by Senator Walters in October of 2012, Walters questioned the wisdom of creating a state-run retirement pension plan for private-sector workers. The bill, SB 1234, established the California Secure Choice Retirement Savings Program for private-sector workers that requires employers that may not offer retirement plans to participate in the program.
Walters is the co-founder of the California Women’s Leadership Association (CWLA.) She currently serves on the Board of the Orange County Gang Reduction Intervention Program (G.R.I.P.). She has also served on the Boards of the National Association of Women Business Owners (NAWBO,) the Laguna Niguel Republican Women Federated, the American Cancer Society, and the South Coast Medical Center Foundation.
In July 2013 State Sen. Mimi Walters announced that she plans to run for the 45th Congressional District seat retiring U.S. Rep. John Campbell (R-Irvine) will vacate next year.
2010 California State Treasurer election
In January 2010, Walters announced that she would run for California State Treasurer against Democratic Incumbent Bill Lockyer. She became Republican Party nominee for State Treasurer the following June.
Investigation by the Fair Political Practices Commission
In early 2012, the Fair Political Practice Commission opened an inquiry as to whether Walters violated conflict-of-interest laws when her office assisted constituents who were having problems receiving feedback from California prison officials regarding the status of a financial claim that Senator Walters husband ultimately had an economic interest in.
The inquiry was disclosed in a written notice to Walters' attorney by Gary Winuk, chief of enforcement for the state Fair Political Practices Commission. He wrote that his office "will be pursuing an investigation regarding whether or not Sen. Walters violated the Political Reform Act's conflict-of-interest prohibitions."
The FPPC inquiry ultimately found that there was no wrongdoing on part of Senator Walters or her staff. 
2012 California State Senate race
On September 20, 2012, Democratic candidate Steven R. Young filed a petition of extraordinary writ seeking declaratory relief to the California Secretary of State to exclude opponent Mimi Walters from the 2012 election ballot for failing to establish a clear residency status in the district she was running in. Under state law, state legislators are required to live in the districts they represent.
Walters and her family have long been associated with Laguna Niguel, where she served on the City Council and was elected to two terms in the Assembly and one in the Senate. But last year, the new California Citizens Redistricting Commission re-drew the state’s legislative districts. To run in the newly drawn 37th Senate District, Walters says she moved to Irvine. Young and two registered Republicans who have joined in the suit say Walters’ move was pure fiction. According to the suit, Walters and her husband, David, have lived in a 14,000-square-foot mansion in Laguna Niguel since 1999. Then, this year, the suit says that Walters changed her voter registration to reflect that she’s living in a 570-square-foot apartment in Irvine with no dishwasher or washer/dryer hook ups.
A Sacramento County Superior Court judge denied Young's petition to have Walters' name removed from the ballot.
2014 Candidate For Congress
On July 2, 2013, Senator Walters formally announced her candidacy for Congress, replacing Congressman John Campbell who announced he would not be seeking another term.  Demonstrating her strong candidacy for California's 45th Congressional District, Walters was quickly named one of the National Republican Congressional Committee's (NRCC) most promising candidates and placed in the Contender category of their "Young Guns" programs. In September 2014, the NRCC named Walters along with 13 other candidates to their Vanguard program. She is running against Democratic candidate Drew Leavens.
