If Sen. John McCain (R-Ariz.) wants to make his primary opponent J.D. Hayworth flinch at embracing the conservative fringe, he’s got work to do. Hayworth sat for a CPAC interviewwith the John Birch Society-affiliated Liberty News Network, right in front of the JBS booth. “There is every indication,” write the Birchers, “that Hayworth’s challenge to McCain in the primary election for the Senate will prompt the four-term incumbent to mute or outright reverse his liberal stance on issues such as climate change, the war in Iraq and Afghanistan, gays in the military, and the bailout of banks.”
