Sen. Ted Cruz has a busy weekend planned. Not only is he confirmed to headline a Texas conference for state legislators hosted by fake historian David Barton, he is also confirmed to speak at a conference of anti-Muslim activists and right-wing muckrakers in Florida hosted by leading Islamophobe David Horowitz .

Warren Throckmorton reports that Cruz is scheduled to speak at David Barton’s “ProFamily Legislators Conference” along with effusive conspiracy thoerist Glenn Beck, master voter suppressor and now Family Research Council bigwig Ken Blackwell, FRC vice president and radical anti-Islam activist General Jerry Boykin, and anti-gay, anti-Islam activist Rabbi Daniel Lapin. But perhaps the most questions for Cruz should come around accepting an invitation from Barton, who routinely pushes junk science and history and who just this week found himself in hot water among conservatives for telling veterans that it’s unbiblical to have PTSD.

Cruz is also set to join Rep. Louie Gohmert at “David Horowitz’s Restoration Weekend,” along with Horowitz’s fellow anti-Islam activists Pamela Geller, Robert Spencer, Erick Stakelbeck and Daniel Pipes; right-wing pundits Ann Coulter and Ben Shapiro; “voter fraud” truther Catherine Engelbrecht ; erstwhile Christian Coalition leader and Jack Abramoff pal Ralph Reed; prankster/martyr James O’Keefe; and rising right-wing star Dr. Ben Carson.

Previous “restoration weekends” have similarly allowed sitting members of Congress – including Sen. Jeff Sessions, Sen. Jim DeMint, Rep. Steve King and Rep. Michelle Bachmann — to mingle with anti-Islam leaders inluding Geert Wilders, Frank Gaffney, Andrew McCarthy and Pastor John Hagee.

While Horowitz’s summit includes a wide variety of far-right activists, its real star power comes from its Islamophobe coalition.

Horowitz himself has built his career on tying American progressives and mainstream Muslims to radical Islam. He’s the editor of FrontPage magazine and has reportedly funded Robert Spencer’s JihadWatch website. Horowitz was a leader of the smear campaign against former Hillary Clinton aide Huma Abedin, who anti-Islam activists accused of being a Muslim Brotherhood agent sent to “penetrate” the US government . Horowitz alleged that Abedin, who is married to former Rep. Anthony Weiner, was a “Muslim Brotherhood operative” and “been given a special dispensation to marry a Jew so she can infiltrate our government.” He has also accused anti-tax activist Grover Norquist, whose wife is Muslim, of secretly practicing Islam and leading a Muslim Brotherhood “infiltration” of the Republican Party, and believes that teachers’ unions are pushing an “infiltration of Islamic Jihadist doctrines” in the public schools.

Geller is also one of the most vocal figures on the anti-Muslim right. It was Geller who dreamed up and drove the “Ground Zero Mosque” controversy in the summer of 2010. Like Horowitz, Geller sees Islamist infiltration wherever she looks, including theWhite House, public schools, the media, and even the Conservative Political Action Committee (thanks, of course to Norquist). Geller frequently suggests that President Obama is secretly Muslim and has even theorized that the president is the love child of Malcolm X.

Geller even attempted to justify Anders Breivik’s massacre at a Norwegian summer camp (which she initially, of course, blamed on Muslims), writing that the victims would have become “future leaders of the party responsible for flooding Norway with Muslims who refuse to assimilate, who commit major violence against Norwegian natives including violent gang rapes, with impunity, and who live on the dole.” Breivik had extensively cited Geller’s work in his anti-Islam manifesto.

Spencer is another one of the anti-Muslim movement’s leading lights, and also sees sneaking radical Islam in in the “Sharia-compliant” CPAC , the Obama administration,the media, TLC reality shows and progressives, whom he argues are “in league with Islamic supremacists” because of their shared dislike of America and western civilization.

To give you an idea of just how willing Spencer and Geller are to run with any anti-Muslim conspiracy theory, no matter how ridiculous, this month both gleefully picked up a story from New York’s local CBS station that alleged that members of the Muslim Brotherhood in Egypt were dipping puppies in gasoline and lighting them on fire in order to make puppy bombs. CBS quickly retracted the story, which was sourced to a Facebook message. But the story so perfectly fit Geller and Spencer’s hysterical anti-Muslim narrative that neither has updated their blog post.

We hope that Cruz at least won’t fall for the puppy bombs story. It’s sad enough to ruin what could have been great weekend.
