Note from Senior Management:

We rarely–if ever–publish “open letters” at Breitbart News. This editorial policy came directly from Andrew Breitbart himself. However, given the enormity of today’s primaries, the intensity of the internal debate raging within the Republican party, and the stature of Brent Bozell in the conservative movement, we have decided to make an exception in this instance.

*****

I’ve endorsed Ted Cruz. I was a contributor to National Review’s Against Trump symposium at the beginning of the year.

Sarah Palin, Ben Carson, Mike Huckabee and Phyllis Schlafly—you are friends and allies, serious men and women for whom I have great respect. You and other conservatives disagreed.

I pen this open letter to you.

Even those of us who oppose Trump understand that he’s tapping into something that has exploded onto the national scene: disenchantment, even white-hot rage among the Republican base with the party’s establishment and the Washington status quo. You and I understand this because we were taking on the weak-kneed GOP leadership many, many years ago, back when Donald Trump was donating to Bill and Hillary Clinton.

Is Donald Trump the answer? That question’s on everyone’s mind. But there needs to be another question answered first: Does Donald Trump mean a word he says? Are conservative leaders supporting Trump prepared to live with the consequences if he doesn’t?

Many critics have outlined the innumerable left-wing positions and candidates Trump championed before he got in this race. It’s worth recalling some of them now: Trump not only supported but bankrolled amnesty. He supported taxpayer funding of Planned Parenthood. He supported not just abortion but partial-birth abortion. He was open to gay marriage. He supported government-funded universal healthcare.

He supported eminent domain for (his) private gain. He supported the Wall Street bailout. He supported “assault weapons” bans. He applauded President Obama for doing a “great job.” He congratulated Secretary of State Hillary Clinton for doing a “good job.” He financially helped the Democrats pass Obamacare. Trump was a registered Democrat when that party was being led by the likes of Nancy Pelosi and Harry Reid, donating heavily during President Obama’s tenure. He’s bankrolled Democrats like Jimmy Carter, Rahm Emmanuel, Anthony Weiner, Terry McAuliffe, Chuck Schumer, Charlie Rangel, Ted Kennedy and John Kerry, to name a few.

But Trump said he’s changed. On everything. Overnight. Just in time for the GOP nomination fight.

Really?

Let’s look at Mr. Trump’s record during this campaign. He’s declared his support for single-payer healthcare. That puts him to the left of Obamacare. He’s re-declared his support for Planned Parenthood. He’s re-supporting tax increases. He’s supported crony capitalism. He’s endorsed “touchback” amnesty. He wants the U.S. to break the Geneva Convention. He’s “neutral” on Israel and Palestine. He wants South Korea and Japan to have nuclear arsenals.

Paul Krugman loves Trump’s big government economic plan for the simple reason that big government will remain under President Trump.

Two weeks ago, Mr. Trump took the left’s side in the North Carolina transgender bathroom controversy.

Last week Mr. Trump announced—guess what?—he’s not just pro-abortion, he wants the pro-life plank in the GOP platform removed, thus divorcing the Republican Party from the pro-life movement. Sarah, Ben, Mike, Phyllis: How can you still support this man? He has now thrown you under the bus, embracing an agenda you’ve spent your entire career opposing. Can you accept that betrayal?

What will you tell your supporters when the man you endorsed enacts an agenda that horrifies them?

As the Republican primaries draw to some sort of conclusion, right now Trump is surrounding himself with GOP establishment types, trying to assure them he doesn’t really mean many of the things he’s said, claiming that much of his campaign is just posturing.

Posturing to whom?

Top Trump aide Paul Manafort is telling GOP establishment bosses behind closed doors that his boss is “a real different guy.” His campaign openly touts his chameleon-like character as some sort of general election advantage.

Is someone with no discernible principles the candidate you want leading the Republican Party and taking on the Democrats in 2016?

Is someone who consistently lies about principles and positions he doesn’t hold worthy of your support?

If Trump becomes the nominee, and enacts the policies he’s now championing, will conservatives who chose to aid and abet Mr. Trump be able to live with their decision?

When it comes time to nominate a new Supreme Court Justice, and President Trump names his radically pro-abortion sister, as he’s suggested he would, or some other radically pro-abortion pro- Planned Parenthood jurist, as we know he will, will you accept that you helped him do that?

When President Trump shocks the civilized world by killing the children of terrorists, arming nations with nuclear weapons (you don’t think Russia won’t do likewise with its allies?) and breaking the Geneva Convention (God help our men and women captured by our enemies who will do the same) will you live with that?

When Big Government, crony capitalism — the corruption of government that triggered his movement — continue unabated for the simple reason he’s offered no plan to stop it, will you accept the blame for having supported it?

This isn’t about purity. It’s about basic sanity.

Do the most courageous thing you’ve ever done, in a lifetime of bravery. Retract your endorsement.
