“Three top Republican House members have written a book that repeatedly criticizes former GOP leaders as well as President Obama,” reports the Washington Post. “In ‘Young Guns,’ scheduled for release Sept. 14, Reps. Eric Cantor (Va.), Kevin McCarthy (Calif.) and Paul D. Ryan (Wis.) cast the Republican congressional leaders who preceded them as a group that “betrayed its principles” and was plagued by ‘failures from high-profile ethics lapses to the inability to rein in spending or even slow the growth of government.’ ”

Good point! And one we’ve made several times at Cato.

But how credible are the messengers? Once you ruin a brand, it can take a long time to restore it. And part of the solution is owning up to your own errors, not just pointing the fingers.

In this case, I’m sorry to discover that Reps. Cantor and Ryan both voted for the Bush administration’s No Child Left Behind Act in 2001, expanding federal control over education. They both voted for the costly Iraq war in 2002. They both voted for the Medicare Prescription Drug, Improvement, and Modernization Act in 2003, which was projected to add more than $700 billion to Medicare costs over the following decade. They both voted for the Emergency Economic Stabilization Act of 2008, which included the $700 billion TARP bailout. (Rep. McCarthy, who joined the House in 2007, voted against TARP.)

To be fair, all three of the authors get A’s and B’s in the annual ratings of Congress by the National Taxpayers Union, which means they have better records on spending than most of their colleagues. But I’ll be curious to see if the book admits that any of the near-trillion-dollar votes discussed above were mistakes — not just by the departed Bush, Hastert, and DeLay but by many Republican members of Congress.
