[1] Aside from his work at National Review, Sobran spent 21 years as a commentator on the CBS Radio Spectrum program series.

[8][9] In response to his firing, Sobran claimed that Buckley told him to "stop antagonizing the Zionist crowd" and accused him of libel and moral incapacitation.

[2] Sobran was named the Constitution Party's vice presidential nominee in 2000, but withdrew later that year due to scheduling conflicts.

[13]) However, the magazine's editor, Scott McConnell, withdrew the offer when Sobran refused to cancel his appearance before the Institute for Historical Review, a leading Holocaust-denying group.

[1] In 2001 and 2003, Sobran spoke at conferences organized by David Irving and shared the podium with Paul Fromm, Charles D. Provan, and Mark Weber, director of the Institute for Historical Review.

[15] Writing in National Review, Matthew Scully said: "His appearance before that sorry outfit a few years ago [...] remains impossible to explain, at least if you're trying to absolve him".

Sobran died in a nursing home in Fairfax, Virginia, on September 30, 2010, of kidney failure due to diabetes.

[1][2] Throughout much of his career, Sobran identified as a paleoconservative like his colleagues Samuel T. Francis, Pat Buchanan, and Peter Gemma.

[2] In 2002, Sobran announced his philosophical and political shift to libertarianism (paleolibertarian anarcho-capitalism), citing inspiration by theorists Murray Rothbard and Hans-Hermann Hoppe.

[citation needed] Asked to summarize his views, Sobran said once, "I won't be satisfied until the Church resumes burning for heresy" — a remark that Buchanan's biographer Timothy Stanley described as "funny, offensive and honest".

He also claimed that the official number of Holocaust victims was inaccurate and that Nazi Germany was not intent on racial extermination.

[23] At the time of his death, Sobran was working on two books, one concerning Abraham Lincoln's presidency and the United States Constitution and another about de Vere's poetry.
