He made a name for himself supporting candidate, then nominee, and finally President Donald Trump in articles, television, and radio appearances, and also on his pro-Trump blog and quarterly journal. Now, Julius Krein is writing off Trump's "disgraceful administration," and urging "anyone who once supported him as I did to stop defending the 45th president."

In a New York Times op-ed titled "I Voted for Trump. And I Sorely Regret It," Krein said he was attracted to Trump during the campaign due to his "willingness to move past partisan stalemates" and because he "forthrightly addressed the foreign policy failures of both parties, such as the debacles in Iraq and Libya." Krein admitted he was aware that Trump's statements on immigration were "often needlessly inflammatory" and his "policy positions were poorly defined," but said he gave Trump "the benefit of the doubt."

Seven months into his presidency, and following Trump's remarks on Charlottesville, Krein said it's now clear his "optimism was unfounded" and Trump's "increasingly appalling conduct will continue to repel anyone who might once have been inclined to work with him." By the day, Trump's behavior is growing "only more reprehensible," and his administration has "no significant accomplishments," Krein added. While he pins some of the blame for Trump's disastrous presidency on the media and the Republican Party, "the administration has committed too many unforced errors and deserves most of the blame for its failures."
