Republicans and conservatives who do not vote for Donald Trump next month are helping Hillary Clinton get into the White House — and playing with fire as to the future of the U.S. Supreme Court, according to former Sen. Rick Santorum, R-Pa.

"Some conservatives have a problem with Donald Trump," Santorum wrote in an opinion piece published by Conservative HQ. "Many of them have stood on purist principle to declare Never Trump.

"But by declaring Never Trump, they have declared they are sitting out this election at a time we all need to coalesce around the candidate that has not only vowed, but has produced, a list of outstanding nominees for the Supreme Court.

"In the end the court is everything. I don't want to be to blame for the wreckage we all know would come through a Clinton Supreme Court. I want to look myself in the mirror knowing I did everything I could to stop it. And that is why this conservative will be voting for Donald J. Trump this November."

Santorum, a two-time presidential candidate, said during Clinton's years as a U.S. senator, she "showed her true colors leading the charge on abortion, opposing sanctions on Iran's nuclear program, and voting to raise taxes, bail out Wall Street, and explode the size of government."

"Her record as a senator, and more recently as secretary of state, is one that should excite even the most hardened leftist," he said. "But this is exactly why every conservative should oppose her."
