"Republican leaders in Washington, DC are signaling they will cave on the fight against Obamacare," Erickson wrote. "GOP Leaders, by caving, are signaling they want us to primary them."
Erickson blamed the GOP's sinking approval ratings on Boehner and other Republican leaders.
"[N]ow that John Boehner and the Orange Man Group of Capitol Hill are the faces of the GOP, Obamacare’s popularity is going back up and the GOP’s popularity is going back down," Erickson wrote.
Boehner's primary opponent, Eric Gurr, has spoken out against comprehensive immigration reform and military intervention in Syria. McConnell's opponent, Matt Bevin, has won Tea Party endorsements in Kentucky.
