Miller writes in his book, Fooled Again, that the 2000 U.S. Presidential election and 2004 U.S. Presidential election were stolen. Miller presents extensive documentation, backed by 56 pages of notes, supporting his contention that the outcome of both elections was altered and controlled by a small minority. He states that the American voting populace can no longer assume that their votes will be accurately assessed, and that the installation of electronic voting machines in state after state is a fundamental flaw in the U.S. electoral system. He appeared in the 2004 documentary Orwell Rolls in His Grave, which focuses on the hidden mechanics of the media, its role as it should be and what it actually is, and how it shapes (to the point of almost controlling) U.S. politics.

He is a signatory to the 9/11 Truth Statement.

His latest book, Loser Take All: Election Fraud and the Subversion of Democracy 2000-2008, covers U.S. election fraud and its acceptance in those years.
