The nation’s ongoing demographic changes signal a “death sentence” for the Republican Party, according to longtime GOP strategist Stuart Stevens.

Mitt Romney’s chief strategist for his 2012 presidential campaign, Stevens worked on four other presidential campaigns. He now says the GOP is looking at a demographic tsunami that threatens to wipe out the party and that the current president is making it worse.

“I had to sit down when I read that a majority of those who are 15-years-old and under in America are non-white. What’s that going to do to the Republican Party? That’s a death sentence,” he says. Stevens, who is currently serving as a consultant for The Lincoln Project, is the author of “It Was All a Lie: How the Republican Party Became Donald Trump.” He recently joined Bryan Schott as a guest on the “Utah Politics” podcast.

He said the current GOP, which he described as a “celebration of white grievance,” is headed down the path of political ruin because of the embrace of nativist and anti-immigration policies by President Donald Trump and his administration.

“Political parties in our system should serve as a circuit breaker function, and nobody pulled the circuit breaker on Trump,” he says.

Stevens is also worried about Trump’s efforts to undermine and call into doubt the legitimacy of the upcoming election, calling the next few months “the most dangerous period in American history since the Civil War.”
