Caitlyn explained in a statement:
"California has been my home for nearly 50 years. I came here because I knew that anyone, regardless of their background or station in life, could turn their dreams into reality.
"But for the past decade, we have seen the glimmer of the Golden State reduced by one-party rule that places politics over progress and special interests over people. Sacramento needs an honest leader with a clear vision.
"l have been a compassionate disrupter throughout my life, from representing the United States and winning a gold medal at the Olympics to helping advance the movement for equality. As Californians, we face a now-or-never opportunity to fundamentally fix our state before it's too late.
