Defeating the former Senate and House GOP campaign committee heads would be a top trophy for conservative insurgents. But with just over two weeks until Election Day, Sen. John Cornyn (R-Texas) and Rep. Pete Sessions (R-Texas) are both heavy favorites against their primary opponents.

Texas Republicans laugh that gadfly Rep. Steve Stockman’s (R-Texas) challenge to Cornyn has been a comedy of errors. Tea Party leader Katrina Pierson (R) has failed to gain any real traction against Sessions as she’s struggled with fundraising and name recognition.

Both veteran lawmakers have run strong campaigns, raised huge sums of money and have given conservatives few reasons to reject them. Cornyn, the Senate minority whip and former chairman of the National Republican Senatorial Committee, has raised nearly $10 million for the race. Sessions, the Rules Committee chairman and former head of the National Republican Congressional Committee, raised $1.3 million for his campaign.

Texas Republicans say the only incumbent member of the delegation with a real race on his hands is Rep. Ralph Hall (R-Texas) — and that’s being driven by Hall’s age, not ideology.
