A handful of conservative media, including the Drudge Report and radio talker Rush Limbaugh, are being singled out for instigating the 2016 "voter insurrection" that helped Republican Donald Trump foil Democrat Hillary Clinton's sure-bet march to the White House.

In his upcoming book, Wisconsin conservative radio host Charles J. Sykes gives credit to Drudge, "one of the top five media publishers in the country."

He calls the website, which attracts 1 billion hits a month, "effectively the assignment editor for much of talk radio, many right-leaning websites and a significant portion of the Fox News channel."

While Sykes, a never-Trumper, is critical of Drudge for linking to alt-right sources such as Alex Jones' Infowars.com and World Net Daily, he concedes that it hasn't resulted in a "loss of influence."

Ditto for Rush: "Along with Fox News, Breitbart and Drudge, Limbaugh was [the] loudest and most influential voice setting the table for a voter insurrection."

His book, "How the Right Lost its Mind," published by St. Martin's Press, is due out in October.

Sykes was a conservative radio host in Wisconsin until he retired at the end of the year. He describes himself as a "contrarian conservative."

His book has won advance applause from other conservative critics of the president such as George F. Will.
