Meghan McCain has threatened to leave the Republican Party over social issues, including gay rights.

McCain, the daughter of Arizona Senator John McCain, told the GOP to “wake up” in a Daily Beast editorial.

“Last Tuesday, Mitt Romney lost – and he lost big,” McCain wrote. “As Republicans, we lost again. I felt sad, exhausted, beaten down, and heartbroken. It was the first time that I considered that the Republican Party, which I love so much, might die.”

“For the last four years, I've been calling for Republicans to stop concentrating on social issues” such as abortion and gay rights, she said.

“Times are changing. … It's possible to maintain the core values of this party and evolve when it comes to social issues. Quite frankly, I don't see any other path to success.”

“We can and we must evolve. I don't know exactly how yet, but I for one am ready to spend the next four years helping us get there.”

“If I don't see some changes in the next four years, I'm going to consider registering as an independent in 2016,” she concluded.
