Quotes from Wikipedia:
Lake was a member of the Republican Party until November 3, 2006, when she changed her registration to become an independent. She registered as a Democrat on January 4, 2008, the day after the Iowa Democratic presidential caucuses were won by Obama.Lake returned to being a Republican on January 31, 2012. She explained leaving the Republican Party in 2006 as a reaction to the then-ongoing Iraq and Afghanistan wars. She had supported John Kerry in 2004 and Barack Obama in 2008. She also made several donations to Democratic presidential candidates. After launching her campaign for governor in 2021, Lake cited Trump, Ronald Reagan, and Arizona Republican Party chair Kelli Ward, all former Democrats, as precedent for her party-switching.
Lake said: “We drove a stake through the heart of the McCain machine”. Later in early November, Lake participated in a campaign event where she told “McCain Republicans” to “get the hell out!” Lake also called the traditional Republican Party “the party of McCain”, and then stated: “Boy, Arizona has delivered some losers, haven’t they?” Her statements were in contrast to her past description of John McCain (Arizona’s former Republican Senator) four years earlier, after his death, as “courageous”, “a war hero, icon and a force to be reckoned with”.
Lake grew up as a Catholic. She previously identified as a Buddhist before 2015 according to her friends. As of 2022, she identified as a evangelical Christian.
